Hello,
I hooked up my asuswrt-merlin ASUS RT-AC68U(380.62_1) behind my ISP provider's modem Netgear AC1900(Cox Cable, Nevada, USA). I have a cat5 cable going from the modem lan port into my RT-AC68U wan port .
So far so good.
No matter which server I VPN into, it works for 1 minute and locks out for 30 seconds. Then works for 1 minute and locks out for 30 seconds....etc. With the VPN off, the router works fine.
After doing some searching, the closest I got that explains my issues was in this post online on an AT&T forum:
And finally, I found the problem! It was my router, running DD-WRT. Compounded by the fact that U-verse is issuing a DHCP lease that is good for just 10 minutes! From what I understand, it means every 10 minutes, all connections on my router go dark.
The simple workaround is to run a firewall script:
iptables -I INPUT -p udp --dport 68 -j ACCEPT
to allow the DHCP packet to go through. Go figure!
I could not find any where in the Firewall of the Advance settings to enter the script.
But is this pointing me in the direction of my router problem?
Any input would be appreciated greatly.
Thanks
ps. fyi - DHCP is disabled and the MAC address is cloned on the asuswrt-merlin router.
