Hi all,
I was trying to set up an ISR 871W to bridge the wireless and three wired ports, with IPv4 upstream through a DSL bridge, via DHCP and IPv6 upstream via 6in4 tunnel. The DSL bridge passes me the upstream IP with DHCP (2WIRE DMZ setup).
I got pretty close, but when I tried to configure the wired-wireless bridging things quit working for me. The router can ping things fine with IPv4 or IPv6, but the devices in the LAN can only ping the router IP and are incapable of getting to anything else besides that, including traceroute, no hops possible.
Can anybody spot what I must have missed? I'm not as familiar with the ISR products yet.
Matthew.

Hello Matthew,
I do not see any static route for IPv4 traffic, do you obtain refault route via DHCP?
Can you ping internet from router?
#ping 8.8.8.8
Can you provide output of these command when you are trying access internet from PC.
#show ip int brief
#show ip route
#show ip nat translation
Best Regards

Pinging the upstream default GW and the upstream DNS works fine from IOS, but fails from nodes behind the NAT + Bridge. The setup does work without bridge enabled, but then you can't connect between the wired and wireless segments after that. I'll get the other outputs collected and post them also.
