Good work! Thanks!
 
Thanks! Just downloaded. The R7800 is the most reliable router I've owned and has pretty decent range on the 5Ghz band and is enough to cover our entire condo from the router on one side to the balcony all the way to the other side of the condo (of course, the 2.4 band goes even further). I've been a fan of your firmware for a quite a while now. It's solid.
 
After contacting the admin / mod, I was able to comment and like your Voxel post. Thank you very much, today I have donated to you, although not much, but my appreciation for what you are doing. Thank you again !
From Gg trans !

Ignore it was my firewall blocking due to certificate issue. Managed to grab the firmware. Its just like a snap. It makes the flashing like a snap .

Thanks a lot Voxel. Without you i dont think netgear routers may not have such popularity.

I am waiting for the ax series of their line up from Qualcomm. I even raised why did they choose brodcom over Qualcomm and they refused to answer on netgear tech chat live session i used to attend every Friday and i believe it still happening.

Just interesting. R7800 is still most popular from the list of routers supported by me. 15 min after publishing this thread and about 100 downloads... First is from Arizona. Greetings Arizona ;).

Thank you for your latest firmware so far I have had no problems. A question if anyone can answer this. Is there any way to get line stats from a modem (vigor 130) to be available through the wan port. Its enabled modem side but the IP is not exposed to the router to access it. The only way is to disconnect from the Wan port and plug it into the Lan port.
Thank You Voxel.

On a router using standard iptables, you could easily do the following to access the modem web GUI - i.e. 192.168.2.1 is the modem IP address:
Code:
ifconfig $(nvram get wan_ifname):1 192.168.2.2 netmask 255.255.255.0

iptables -t nat -I POSTROUTING -s ! $(nvram get lan_ipaddr) -d 192.168.2.1 -j SNAT --to 192.168.2.2
Unfortunately, Netgear don't use standard iptables, so this method I believe can work for a short time until the firewall stops it...

I'm afraid I can't be of any further help...
 
If tarassippo's iptables commands do work, then you can simply put then in a script called /opt/scripts/firewall-start.sh (and make that script executable).
This way the rules are re-added everytime the firewall is restarted.

I do see a potential conflict with OpenVPN server though, as that also uses the range 192.168.2.x/24.
(if it is enabled, and if the regular lan subnet is 192.168.1.x/24)

Thanks for your help I have tried the commands, But unfortunately the second command comes up with an error. Router IP 192.168.1.1 Modem 192.168.2.1.

root@R7800:/$ iptables -t nat -I POSTROUTING -s ! $(nvram get lan_ipaddr) -d 192.168.2.1 -j SNAT --to 192.168.2.2
Bad argument `192.168.1.1'
 
The ! should be in front of the -s

Code:
iptables -t nat -I POSTROUTING ! -s $(nvram get lan_ipaddr) -d 192.168.2.1 -j SNAT --to 192.168.2.2

Code:
iptables -t nat -I POSTROUTING ! -s $(nvram get lan_ipaddr) -d 192.168.2.1 -j SNAT --to 192.168.2.2

That command worked :):) but unfortunately, I can't access the modem on 192.168.2.1 But I can access the router page from 192.168.2.2 and obviously 192.168.1.1.
 
Try these:
Code:
ifconfig $(nvram get wan_ifname):1 192.168.2.2 netmask 255.255.255.0

iptables -t nat -I POSTROUTING -o $(nvram get wan_ifname) -j MASQUERADE
 
Try these:
Code:
ifconfig $(nvram get wan_ifname):1 192.168.2.2 netmask 255.255.255.0

iptables -t nat -I POSTROUTING -o $(nvram get wan_ifname) -j MASQUERADE

Commands work but no access to 192.168.2.1 (modem) still have access to the Router login from both IP addresses but not the modem.
