Funny situation....

| Hello,
Having an odd problem between to point-to-point sites. I have 2 routers, everything seems to be on the up and up. I can ping the routers from each other and I can ping the remote router at site A from a workstation at site B. However, I can't ping site B from a workstation at site A but I can ping router A. I have ip route 0.0.0.0 x.x.x.x and no access-lists configured. Anyone have any ideas ???!!! | |

| Hello,
it looks like it's not finding the route to router B for some reason. Have a look at 'show ip route' to see if the route is known.
Try setting a specific route to router B going out of the interface 'ip route etc serial0'.
Has the interface got an ip address? Set your static route to the far-end ip address rather than just 'ip route etc serial0' etc.
If it still doesn't work then perhaps you could post the configs of both routers?
Regards

| check the pc's default gateway is set to router A's address. | |

| Hi Mat,
ah yes, that would do it. You can tell I'm not a PC man can't you? :-)

I'm not sure exactly what he's got going on here but I just noticed an absence of a routing protocol.... | |

| You don't need a routing protocol when you use just statics, but IP ROUTING may have solved your problem.

| Hello,
why does site 1 serial 0/0 have ppp authentication and chap password set? This is not something that I've seen on a serial (non-dialup) i/f before, but if there's a reason for it then surely it also needs to be set on the serial i/f at site 2?
Regards
Peter | |

| I think it would be nice to get some feedback from Richard.
I agree with Yankee on the static routes, although peter if he can ping between the routers then obviously ppp is working and there isn't an authentication issue - I suspect that now you've mentioned this though he probably can't.
If I was Richard I'd probably do the following -
1. Reconfirm that BOTH sites can ping across the link from the router.
2. If not, disable Chap temporarily using the command "no ppp authentication chap" then retry step 1.
3. If pings are getting across then move to a PC at both ends, ping the local ethernet address, if successful ping the local WAN address, If successful Ping the remote WAN address, If successful ping the remote ethernet address.
If only the first ping works I'd double check the default gateway on the PC's. | |

| You could also try a traceroute/pathping from the host A and see if it gets to router A and beyond...

| Ok I'm assuming that this is a test lab setup in which case I suggest you use the following:
I have eliminated all the crap that is not needed in the configs, and you should be able to erase the startups and reload, then paste these in and do a "copy run start" afterwards on each router.

If its a real live network then you may want to try this out of hours and make sure you backup your running-config for both sites first.
But I have tested this on my Lab and it works
As for what this guy is trying to do with PPP, dialer & access-lists defies all my knowledge | |
|
| I wouldn't waste your time, he's already fixed it!
It is good though having real world Q's to work on. | |

| Dhoooooo, darn and there was I thinking I was posting a fix...aaaaaargh oh well.  |
