HTTP traffic via NAT on 678 DSL router

[fmwoodall]

I have a Cisco 678 DSL router. I have successfully added NAT entries to pass FTP and SMTP traffic through to my server. Even though I set HTTP traffic up the same way, it does not pass through.

Has anyone ever accomplished this? Does anyone know who to do this?

I used the following command:

set nat entry add 10.0.0.249 80

Is there any way to monitor traffic coming to the router so I can see if the port 80 traffic is even reaching the router?

I am running CBOS V2.4.3

Thanks.

do you have ACLs configured? also, upload your config.

Thanks for the response. To my knowledge there are no ACLs (didn't know the 678 had ACLs). There are no filters on the 678. The target internal node is 10.0.0.249. All ports work ok except port 80.
