Hi,

I am trying to configure secondary WAN. My setup is with Load balanced option.
I have both WAN connected. As soon as I disconnect the WAN from WAN port (PPPoE) I loose the access to the internet.

The USB Stick WAN is connected and I can still bing the Gateway and the USB 3 WAN IP.
I am on Merlin Firmware 380.70 in AC88U.

I think it must be something to a firewall routing or something. Maybe because I have the local ip with 172.16. Of could be related to DNSCRYPT.

Please share here what do you think. I tested the SIM in my phone and it is working
Most grateful for any ideas on where I went wrong.

Thank you so much!
 
Load Balanced is not intended for failure handling, it's intended for balancing the load between both connections as the name imply.

Thank you. I ended to try this because I was not sure that the dongle is connecting.

What I need is to use USB 3 with internet as failover of WAN.

So, even I have IP, DNS on dongle, the internet is not working when I remove the cable from WAN port with failover as setup (WAN port main, failover to dongle in USB3 port).

Anyone know how to fix this?
Thank you so much!

Did you try to test in Fail Over mode? That mode is most suited to your needs. ;)

Yes, that was the first thing tried. And because it was not working, I balanced mode.
Please, were I should take a look to make failover working?
I have connection even in failover on USB as secondary WAN, but I have no internet when remove the cable from main WAN port.
Thank you. All the best!

For something as fundamental as this to fail, there is a deeper issue.

What scripts, features or other options do you have enabled or using beyond the defaults? What firmware are you using right now?

When was the last time you did a full reset to factory defaults followed by a minimal and manual config to secure the router and connect to your ISP?

It does not seem to me that your router is in a good/known state right now. I would recommend a full M&M Config on your router without any additional scripts, options or other features enabled past defaults. To verify that the failover function works at all.

After that point, you can begin to add additional features one by one, testing between each one, including doing a reboot of the router, to make sure everything stays working as you need it to. You may find that you can enable all the features eventually without any failures. That would prove that the M&M Config was what was needed.

The link above shows why a reset may be required.
 
Thank you. I am on Merlin Firmware 380.70 in AC88U. I think it must be something to a firewall routing or something. Maybe because I have the local ip with 172.16. Of could be related to DNSCRYPT 1.1.1.1.

It is a option to do a factory reset, but before I want to be sure that I have tried all before and without success.

DNSCRYPT DoH, Entware with NZBGet, Transmission, PHP, lighttpd server, VPN Server, VPN Client, IPSET_Block (HackerPorts), SWAP.
That will be all main services on the router.

Edit!: With WAN port empty and secondary USB as WAN on I have ping only to IP obtained and to DNS.

Thank you,

Firmware v380.70? My friend, you need to flash to a newer, more secure, more robust, more tested and more feature-rich version. :)

I recommend at least RMerlin 384.11_2. (Note that there is a very stable alpha release 384.12 Alpha1 too).

DNSCrypt will certainly not be needed on the latest RMerlin firmware (he was never a fan and it seems rightly so).

You should also look into the amtm script and the scripts it supports too. All very useful and working very well together.

I would also recommend you install Entware via amtm (and, if you decide to use Diversion, via Diversion instead) rather than NZBGet.

Below are some of the links you should find useful to get your router to a modern firmware release and update and streamline many of the other services you have too (note; I am not familiar at all with Transmission).

I have tried to put them in the order you will need them. :)

Thank you so much for your post. I was waiting for User NVRAM Save/Restore Utility (R26.2) to be available for newer versions of Merlin.
I like that DNSCrypt is included, but after entering all settings on newer firmware I would like to save those settings with a utility like I mention.

I will save you post for later. Thank you again! All the best!

You will be waiting for a very long time. That project has been effectively abandoned for the latest firmware and routers.

You also misread what I wrote about DNSCrypt. It is not included. DoT has effectively replaced it. :)
 
In the meantime I did a factory reset, updated to 384.11_2 and then again factory reset. I inserted the stick and set it as fail-over.
And I have same problem. I have I without internet. Please take a look at screenshots attashed.
Could you please share your ideas to try?

Edit1: I tried again with factory default, because at the moment of screenshots I changed the default IP. So is not working with default 192.168 too.
Thank you so much!

FWIW: a couple of weeks ago someone decided to upgrade my fiber connection, however the SFP in my fiber converter decided to fail at the same time, so I lost internet connection. First I got a USB stick and SIM card, 4G to be more precise, and I never got it working at all. I think it is only a very few USB sticks that might work and they more or less has to have a web server inside that controls the USB stick modem properties...

I ended up with a Netgear MR1100, which is a battery operated mobile router which happens to have, among other features, an ethernet port which I connected to my AC88 router. Funny thing though, only lower ports works (1-4). Anyway after this everything have worked like a charm! Expensive solution though, but it works, and well the mobile router can be a good thing to have in the future. Btw the Netgear MR1100 is well not future proof at all, but it is realy fast device, I got great speeds for download.

Thanks. What is funny is that I have IP at WAN and I have DNS too, and ping to them working. Only internet is not working, ping to those IP is working.
 
It is already disabled. I think I need a route/ tunnel, But I don't know how to do it. I say that because network manager see that the dongle is connected to the internet so is not a incompatibility with the dongle.

Thanks for the unsolicited PM.

You should be able to check that the Dual-WAN RPDB rules and the Dual-WAN fwmark rules are correct.

I have just plugged in my USB modem to my development unit RT-AC86U with Dual-WAN Load-Balance 9:1 ratio and traffic is correctly flowing over both WAN0 and WAN1 without the need for additional routing rules.
Code:

@Martineau, please accept my apologies for the unsolicited PM. I will not do this again.
And thank you for post.

I hanged to 9:1 load balance, and I have the both WAN connected, but when I remove the WAN I have no internet on USB.

Below is my output:

I'm not sure why there appears to be three interfaces in your OUTPUT chain, yet apparently there are no hits?

However, you should be able to check if data retrieval is possible via both WAN interfaces:
Code:
curl --interface eth3 --connect-timeout 5 -s "http://ipecho.net/plain";echo

curl --interface ppp0 --connect-timeout 5 -s "http://ipecho.net/plain";echo
As per post #2 for the current firmware, if say WAN0 is DOWN, then the firmware (v384.12_Alpha) will revert to a single WAN configuration i.e. the RPDB rules are removed, along with the 9:1 ratio.

So if you don't get similar messages in Syslog
Code:
RT-AC86U kernel: eth0 (Int switch port: 3) (Logical Port: 3) Link DOWN.
RT-AC86U kernel: ===> Activate Deep Green Mode

then I suggest you upgrade from v380.70
 
Thank you Martineau.
Long story short: I started this thread when I was on 380.79. I received suggestion to upgrade to 384. I did a factory reset then update to 384.11_2, again factory reset.

And, o this new environment I set up the PPPoE, admin password, WiFi and inserted only the stick with internet. Then I tried with failover (this is what I need) and, after, with load balance.

The result was the same: I can see the USB WAN connected, but I can ping only it's WAN IP or DNS. Internet is still offline.

Now I finished setup customizations. One of them is a bind IP of my LAN as one of interfaces.

Code:
ASUSWRT-Merlin RT-AC88U 384.11-2 Sat May 18 03:33:22 UTC 2019
root@ac:/tmp/home/root# curl --interface eth3 --connect-timeout 5 -s "http://ipecho.net/plain";echo

root@ac:/tmp/home/root# curl --interface ppp0 --connect-timeout 5 -s "http://ipecho.net/plain";echo
188.25.179.215
root@ac:/tmp/home/root#

And in failover mode here is my sys log with warnings level mode, after removing the main WAN:

Code:
Jun  3 00:50:44 ovpn-client1[22106]: Connection reset, restarting [0]
Jun  3 00:51:00 kernel: cdc_ether 1-1:1.0: eth3: kevent 12 may have been dropped
Jun  3 00:51:34 pppd[30362]: Timeout waiting for PADO packets

Even in connection it displays as connected, no internet.

Thank you for help!
