It's exactly what I want as I was looking to route through the wan for Netflix and Amazon prime

Just to report method three is working for me.

I'm based in the UK and to start with only amazon prime would work, with 'some' Netflix shows playing without issue. After a bit of investigation I found ipv4-c001-bhx003-virginmedia-isp.1.oca.nflxvideo.net seemed to be causing my problems.
traced it back to ASN5089 which is maintained by my ISP

I've ended up with the following

load_AMAZON_ipset_iface.sh 0 AMAZON-EU EU
load_ASN_ipset_iface.sh 0 NETFLIX-2906 AS2906
load_ASN_ipset_iface.sh 0 NETFLIX-5089 AS5089
load_ASN_ipset_iface.sh 0 NETFLIX-14618 AS14618

Hopefully that's not opened up too much.

Thanks again!

I suspect it may be a Content Delivery Network issue where Netflix is caching content on servers your ISP is hosting?

Anyways, the DNSMASQ method may eliminate the need for the three ASN scripts. I also included amazonaws.com domain in the example below:

Code:
sh load_DNSMASQ_ipset_iface.sh 0 NETFLIX amazonaws.com,netflix.com,nflxext.com,nflximg.net,nflxso.net,nflxvideo.net
 
@Xentrk you helped me setup comcast "at home" thru the VPN forums using option 3 of your install. A few days ago my router (RT-AC86U) somehow resetted and I had to setup all over again. This time around, I will not be using Diversion/Skynet, however, I did re-install amtm to include your script again. I have finally finish setting up my router and for some odd reason...comcast at home is not working with your script. Hulu and Netflix are working flawlessly.

In the past, all I did was to add the the ASN script and added the ASN command (sh /jffs/scripts/x3mRouting/load_ASN_ipset_iface.sh 0 COMCAST AS7922) to the nat-start and it started working. I restarted the router and hulu/Netflix works without issues. Can it be that I have the PIA server address set up to "east" coast server? It's odd because it worked in the past.

I use PIA VPN and i'm using option 3 of your script but for whatever reason, comcast at home is not working... any other options you think I can try?

That is peculiar that AS7922 it was working before. I highly recommend you add the router's IP address to the Policy Rules and route it to the WAN.

First thing to check is to make sure the ipset list is populated and the routing rules for COMCAST are being applied.
  1. Use the liststat command to make sure the COMCAST ipset list is being populated.
  2. Run the command iptables -nvL PREROUTING -t mangle --line to see if packets are traversing the chain
The second step is to mine dnsmasq.log or use the follow the log file feature of Diversion to see what domain names are being called when watching Comcast. Then, do an nslookup on the domain name to get the IP address. Run the whob command on the IP address to list the ASN it belongs to or lookup the IP address using bgp toolkit. You may need to add another ASN.
 
The other thing is the order of the iptables rules. They are processed in order. When it was working before, did you have the script for comcast listed before the script for Hulu and NF?

Thanks ...I had made a back up the nat-start file so I have not changed the order of the iptables rules. In the past, I also used both AS7922 and AS7016. I'll continue to work on the steps you mentioned earlier.

You are welcome. Comcast owns 71 AS numbers. Try adding AS7015.
 
Dear all,
I have a problem with my configuration. The german TV Streams should be streamed via OVPNC1 (Germany), the rest should be routed to OVPNC2, except some devices with specific IPs.
I got the AS numbers and populated them Screenshots. I added DNSMASQ as well, but it doen´t work.

But the routing seems to be via OVPNC2 because I got an error, that I am in a the wrong country. What did I wrong ?

edit: I got it worked. You have to add additional urls to DNSMASQ entries e.g. akamaihd.net . Then it works....

Thanks a lot.

When you see a 0 in the pkts and bytes columns, it means no traffic is traversing that chain. No match is occurring. You need to mine dnsmasq to see what domain names are being used. Then, do a nslookup to get the IP address. Then, either use the whob command on the ip address to identify the ASN the ip address belongs to or lookup the IP address on Hurrican Electric BGP Toolkit.

Dear Xentrk,
I already used the BGP Toolkit to get the AS numbers. But that was not enough. I used the programm mediathekview to look at the urls for streaming. These urls I added to DNSMASQ as well as the toplevel domains for the TV broadcaster. maybe a transferred more urls then necessary via OVPNC1 but it seems to work at the moment. I am able to stream :)

But thanks a lot for your support.
If you are interested I can send you the script, that you could add the urls in your help file....


Last question:
The IPs of the guest network are from the same range as from my "normal" network. Any idea to separate it e.g. 192.168.11.0 (normal network) , 192.168.22.0 (Guest) ?
Currently the same rule 192.168.11.0/24 as source is applied to normal network and for guests....

I add a rule for my DSL router, that he can be configured from my asus network. So I allowed everybody to reach the 192.168.0.1 from the normal network. unfortunately the is reachable of the guest network as well. That I don´t want...

Can you post an example or two of the domain names you passed to the script using the dnsmasq method? Thank you.

I tried adding with no luck....I was looking at WinSCP, the configs folder, the dnsmasq file and when I opened it, it has the following line: ipset=/hulu.com/hulustream.com/akamaihd.net/HULU_WEB

What I recommend that you do is mine dnsmasq using the technique and script getdominanames.sh

Installation getdomainnames.sh
Code:
/usr/sbin/curl --retry 3 "https://raw.githubusercontent.com/Xentrk/netflix-vpn-bypass/master/getdomainnames.sh" -o /jffs/scripts/getdomainnames.sh && chmod 755 /jffs/scripts/getdomainnames.sh

1. mv /jffs/scripts/nat-start /jffs/scripts/nat-start.bk
2. Reboot to remove routing rules create by the x3mRouting scripts.
3. Turn off VPN to route all traffic thru the WAN.
4. Navigate to the dnsmasq log file directory. My dnsmasq.log file location is /opt/var/log.
5. Type the command to start capturing domains used by Comcast to the file :

Code:
tail -f dnsmasq.log > Comcast

6. Now, go to the device you are watching Comcast from. If you are streaming from your PC or laptop, close out other applications to minimize collecting domain names for non-Comcast traffic. Navigate around the menu options and watch several videos for a few minutes each to generate traffic and log entries to dnsmasq.log.
7. When done generating Comcast traffic, press ctrl-C to stop logging to the /opt/var/log/Comcast file. Run the getdomainnames.sh script, passing the file name and IP address of the device you were watching Comcast from. For example:

Code:
sh /jffs/scripts/getdomainnames.sh Comast 192.168.1.20

8. This will create a file called Comcast_domains in the /opt/var/log directory. Open the file in an editor to view the domains names collected. The next step is to desk check the file for domains not related to Comcast. These are domains generated by other applications on the LAN client you streamed from. Once you have narrowed down the domains, the next step is to use the top level domain name references in the script using the domain names you captured. For example:

Code:
sh /jffs/scripts/x3mRouting/load_DNSMASQ_ipset_iface.sh 0 COMCAST xfinity.net,comcast.com, etc..

Or, you can analyze the IP addresses for each domain and see what AS number they belong to and use the ASN method.

Thanks again! Got it working by adding the comcast.net/com domains. Really do appreciate all the help on this matter.

Good news. :) Thanks for reporting back. Hopefully it will help someone else in the future.
 
First of all thank you for these awesome scripts which enhances the features of asus routers. :)
I know this script has been specifically made for routing to a VPN.
But I have slightly different use case.
I have two internet connections, both are unlimited but one of it reduces speed after certain usage and that is my primary wan connection.
The other one is truly unlimited and connected on LAN port 4 in Dual WAN+Failover configuration on RT-AC68U.

I want to redirect all Backblaze traffic through this 2nd WAN connection.
I ran this script to create the ipset,
Code:
sh load_ASN_ipset_iface.sh 0 Backblaze AS32354
But in the script there is option only for 1st/default WAN that is WAN 0 and the other 5 are all OpenVPN connections.

How can I use this ipset and configure it to route Backblaze traffic through 2nd WAN connection on the router ?

Routing to WAN1 should work. I'm unable to test using dual WAN though. I looked at some of @Martineau post for references. I'm not sure if the fwmark/bitmask of 0x9000/0x9000 will work. I would need to evaluate the priority number for WAN1 as well. You can test by running the commands below:

Code:
#del current routes assigned to WAN0
sh load_ASN_ipset_iface.sh 0 Backblaze AS32354 del

Code:
#create ipset list Backblaze
sh load_ASN_ipset_.sh Backblaze AS32354

Code:
# WAN1 - Create rule and table for WAN1
ip rule add from 0/0 fwmark 0x9000/0x9000 table wan1 prio 990
ip route flush cache

Code:
#Create routing rule for ipset list
iptables -t mangle -A PREROUTING -i br0 -m set --match-set Backblaze dst -j MARK --set-mark 0x9000/0x9000

See if the routing works. Run the command below to see if any packets are traversing the chain.
Code:
iptables -nvL PREROUTING -t mangle --line

Check RPDB priorities using the command
Code:
ip rule

Backout Changes:
Code:
iptables -t mangle -D PREROUTING -i br0 -m set --match-set Backblaze dst -j MARK --set-mark 0x9000/0x9000
ip rule del fwmark 0x9000/0x9000
ip rule del prio 990

Thank you the detailed steps. The routing is working but traffic is not going through secondary WAN :(
How is the fwmark bitmask calculated. What kind of information do you need to get it right for secondary WAN ?

Thanks again for quick response :)
