Sonicwall behind a Cisco Router with Multiple WAN IPs.


I'm not trying to hijack this thread, but my question is very similar to the actual question, so I guess this is the best place to ask.

My setup is this: commands have been shorted, only to show related config.

Cisco 1900 Router:

gig 0/0 = (p2p to my isp, it's a microwave link)

ip nat ouside

 ip address secondary (Public IP)

 ip address (Local lan)

ip nat inside

ip dns server

ip nat pool CAFE netmask

ip nat inside source list 10 pool CAFE overload

ip route

dialer-list 1 protocol ip permit

access-list 10 permit

access-list 20 permit

access-list 20 permit


X0 = Management

X1 =

X2 = lan)

My question here is. I would like all the Public ips to be routed from Sonicwall. I want the cisco router to only act as a bridge. All the nat would happen on Sonicwall. How do I achieve this?

Should I assign one Public IP to X1 port on sonicwall? should that publish my sonicwall on the internet? And nat accordingly?

Any help on this will be highly appreciated.

    Provide clearer information and we might be able to help, but why even have the Cisco if its just acting as a bridge? There are other discussions on this topic.
