Problems getting out of local network
So I've been fighting this with a few days and can't seem to figure out what is going on. I have a linux box here that I've put Fedora 6/7 (and now DSL 3.4 as well) on and can't seem to get it to ping outside of our network. With 7 I had issues with DHCP but I switched and put 6 on and that solved that problem (switching over to static addressing also solved that) so now I have connectivity within our network (can ping our DNS server as well as resolve outside addresses such as Google). Right now DHCP and a static IP both work for a connection within the network.
So I know that the configuration is fine (double checked the ifcfg-eth0 file as well as resolv.conf and they are set to the right IPs as well as pointing to the correct gateway) and everything seems to work fine locally. If I try to ping Google or any other public address that is pingable it will resolve the IP address but will not get any replies. Also internet traffic does not work (works internally, can access our internal web servers). So I'm trying to determine what is the cause. From all of our Windows boxes the network works fine and we can browse the Internet.
I checked the route statements in Fedora and it has a default gateway of 10.10.10.3 (that's our router) and the proper route statements (a route for our subnet as well as a default gateway to our router).
The only thing I can think of is configuration with our router (Cisco 1811) that I've looked through and can't seem to find anything that may be causing this.
Any help or even ideas would be greatly appreciated. I'll post a copy of the config files (ifcfg-eth0, resolv.conf, route output).
