You aren't losing it. :-) We haven't said our usual answer yet. Send us the configs. Also he never told us anything about subnet masks. Maybe he's doing something weird with them, but probably not. Maybe on the Frame Relay interfaces, he's just mapping to the Ethernet sides and the serial interfaces don't know how to send to each other?? Can he ping or trace route just between the serial interfaces on the routers? I don't think he's told us that. Can the routers ping their own serial interfaces? Probably not. If the routers can't reach (from a L3 point of view) each other's serial interfaces, then Router B can't forward the ICMP TTL from Host B to Router A's serial interface, which is what he said was the problem at one point... I was suspicious of Host B, but we do need to see the router configs too. Does my explanation make sense!? I'm losing it now. :-) Priscilla > >Dave > > Frederico Madeira wrote: > > Dave, > > > > In my network, neither router have routing to wan interface. > If i ping from > > any host on lan to any interface WAN of my network, **the > hosts don4t have > > route to interfaces**.

Yes they do have routing to the WAN, they are CONNECTED to it!

Dave, In my network, neither router have routing to wan interface. If i ping from any host on lan to any interface WAN of my network, the hosts don4t have route to interfaces.

That's strange, but it doesn't matter. You can still do some troubleshooting. Here are some questions to investigate. Why in your testing could Host B send a packet to Host A, but Host B couldn't send a packet to the serial interface on Router A? When Host B sends the traceroute to Host A, it's either sending a UDP or ICMP packet, depending on its operating system. That seems to work. All layers are working. It can send the upper-layer packet and it has a route to Host A. It appears that Host B can't send an ICMP TTL Exceeded message to the serial interface on Router A, however. That's the crux of the problem. (Traceroute depends on the routers and target host sending an ICMP TTL Exceeded message). What other testing have you done with Host B trying to reach the serial interface on Router A? Can Host B ping or traceroute to that address? At what layer does this problem reside? Does Host B really try to send the message? (Use Ethereal to see if it does.) If not, does it have a firewall that's blocking it? Probably not, since it can send a TTL Exceeded to Host A. So it's probably a network-layer problem. Does it have a route to the destiantation IP address (router A's serial interface?) What does "route print" tell you? What does "ipconfig/all" tell you? (assuming Windows) If UNIX, try route -n, netstat -rn, ifconfig. Of is the router somehow blocking the TTL Exceeded? That doesn't seem likely since it works in the other cases. I would focus on Host B. I think he's confused It could be a bug in the router, but something seems odd at Host B, as a first guess.

Check Host B's routing table and configuration. That's what MADMAN was getting at. Also, he suggested you try a ping or traceroute from Router A using Router A's IP address on its Ethernet side. It will probably work then. By default the router uses the IP address for the closest exit interface. You can change the source address that the router uses by using extended ping or extended traceroute. Type ping or trace and enter. That will take you into the extended mode where you can set the source address. Keep us posted. I'm curious to know what you find.

Re: Ping Problems [7:70980]
Hi, Remember that when you ping from the console the source address will be the interface where the packet exists. Therefore I suggest you do an extended ping and specify the source address as the ethernet address. I'm pretty sure you will see this is the problem.
