Blog Memory: Accessing Vigor 120 Modem when bridged with Buffalo WZR-HP-AG300H (DD-WRT)

I found this article http://ip6.com/projects/?p=363

So I just changed the IP address to match the default that the Vigor modem uses:

ifconfig eth1:1 192.168.2.9 netmask 255.0.0.0
iptables -I POSTROUTING -t nat -o eth1 -d 192.0.0.0/8 -j MASQUERADE

It’s not perfect but it’s a start.
