I have a Linksys E3000 router that I'm trying to set up. I've connected the cable from my ISP to the Internet port of the router, and accessed its GUI via the wireless connection (had no other cable). I've edited the Internet setup section to use Static IP and provided the Internet IP address, subnet mask, default gateway, and DNS options as given to me from my ISP.

I expected the internet to be tethered then. From the diagnostic console in the router's web UI I was able to ping outside addresses (namely, 8.8.8.8) successfully. From the laptop I can ping the router's address, but not any outside address, and tracerouting to any outside address goes no further from the router's LAN address, so I guess the problem has something to do with the router forwarding.

The routing table of the router is as follows:

Destinatio LAN IP   Subnet Mask      Gateway          Hop Count   Interface

(WAN Port network)  (my WAN subnet)  0.0.0.0          1           Internet (WAN)
192.168.20.0        255.255.255.0    0.0.0.0          1           LAN & Wireless
0.0.0.0             0.0.0.0          (My ISP Gateway) 1           Internet (WAN)

It seems fine to me, but I still can't access the Internet.

Is there anything that I am not seeing? Is there anything else I have to set up? Has the problem anything to do with not setting it up with the software included in the CD? (because I'm using Linux and the software came for Windows and Mac!) And if not, what is wrong or how can I troubleshoot this problem?

EDIT: The IP address assigned to my WAN port of the router is also unreachable from the LAN...

Can you ping the outside interface of the router? Can you ping 41.78.109.73? 41.78.109.73 is not assigned to your router's outside interface right? Also, just curious but most residential internet setups use a dhcp outside interface. Were you assigned a static IP? –  Jason H May 15 '13 at 12:40
    
@JasonH No I cannot ping that address.. And yes it is assigned to the router outside address. And yes I was assigned a static IP. It's a long story, lazy ISP, bad customer relations, and more politics... –  amyassin May 15 '13 at 12:46
    
@JasonH Oops! Sorry that address is the gateway address given to me by the ISP.. My IP is also unreachable from the LAN... –  amyassin May 15 '13 at 12:50

What happens if you configure your PC with the static IP and other info given to you from your ISP, without using the router? Does that work without problems (ie. is this router specific)? –  bigbadonk420 May 15 '13 at 13:10
    
@bigbadonk420 I just tried that, it works fine without the router. It is router specific... –  amyassin May 15 '13 at 13:12

Routing table is OK.

You must configure NAT to translate local IP addresses to WAN IP address.

Care to expand on how the OP might go about doing that? –  techie007 Aug 31 '13 at 18:16
