cisco1711 & vlans: basic routing issue...

    I can't seem to route THROUGH my cisco1711
    router.


    From inside the router I can ping both the
    internal AND external IPs, as well as any
    IP on the internet. (Although I can't seem
    to traceroute to any of them!)

    Note: The gateway to the internet is the
    FastEthernet2 port!

    But if I connect a server(IP: x.x.x.250),
    into the FastEthernet0 port, I CAN ping:
    x.x.x.246
    x.x.x.249
    x.x.x.250
    But I can NOT ping:
    x.x.x.245


    What am I missing here?

    It doesn't look like anything's wrong on your side. The router with
    the x.x.x.245 address is probably just blocking ICMP echo-replies.
    But it may even be that you're blocking certain types of ICMP replies
    since you can ping some devices but not traceroute to them. Either
    way, this is definitely not a routing issue since you can get to all
    destinations via your default gateway but just can't get the ICMP
    traffic back.

    The traceroute problem is just an unusual side issue.

    The main problem is that Cisco1711 can see everything on the net,
    but anything on the inside of the Cisco1711 can't seem to surf the
    Internet. (ie. the cisco1711 wont let any packets pass through it!)

    Is everything inside definitely set to use x.x.x.249 as the default gateway?
    Also, why is there a no keepalive setting on the fa0?

    Yes, x.x.x.249 is the default for everything inside.

    I've tried using keepalive, but it still doesn't route.

    It has to be something simple, but I don't know what
    to try next?

    ie. It just wont accept the vlan as the default gateway!?!?!

    Correction, it now seems to be working!

    I put keepalive on, but had to wait about 5 minutes before
    all the routing started to work.

    Why would there be such a delay?

    And what does keepalive do?
    (Someone once told me that having keepalive on, sometimes
    causes problems?!?!? Is this true?)
