I have a single host at a site I cannot ping through our WAN interface on the router, yet I can ping any other host on the LAN remotely. This host is reachable and can be pinged locally at the site. When I do a traceroute from the main site, the ping stops at the serial interface of the router. When I check the router for a route to this host, a route exists.
I'm wondering what could be preventing me from communicating with this specific host remotely.
I don't know if this helps but we have several sites set up the same way, and with 3 of the sites we have this problem. The sites that are working have Cisco 2600 series routers. The sites that aren't working have Cisco 1800 series routers. The remote host that we cannot reach is configured statically with 192.168.x.254.
Some assistance troubleshooting would be helpful.
If it has multiple interface and there are multiple subnets involved in your network, then the Linksys must have some sort of static route for your other locations to be able to reach it.
Also, if you have diagram you can post maybe I can help you better.
