You guys, I hate having to ask something so simple, but I"m stuck. I
was away from the old Cisco access routers for a couple of years, and
now all of a sudden I'm needing to use existing equipment to set up
very simple routing tasks -- a local LAN and a gateway router, nothing
more.

I have configured a 4500, a 2621 and a 2514 and at times I get them to
route from PCs on the LAN, out to the Internet but when I do get it
it's dumb luck. A 2514 and a 2621 for just in case, were working
great in my lab and when I took them to the client they just by God
would not route. With everybody watching over my shoulder wouldn't
you know.... Testing everything in sight, it is clear that is it my
configuration that's wrong, and I do not know where the problem is.
Has to be simple.

May I please post this 2514 sh ru and ask if someone would look at it
-- I think the problem will probably just leap out at somebody who is
fresh with this stuff.

Thanks Guys,

Bob W

If default routing is not working then try:


ip classless
no ip default-gateway 192.168.0.1
no ip route 0.0.0.0 0.0.0.0 Ethernet1
ip route 0.0.0.0 0.0.0.0 192.168.0.1

Thanks, Merv. It still not working. I can ping both router
interfaces from either side, and I can ping everything in both
directions from within the router, but I still can't ping through. A
PC with the address 200.200.200.3, GW 200.200.200.1, can't ping
192.168.0.1...

Here's what I show after making the changes you suggested:

!
router rip
version 2
network 200.200.200.0
network 192.168.0.0
no auto-summary

You cannot and should not route RFC1918 addresses to the internet. Either
use NAT or use public addresses.

Yesssss! I took a LinkSys and gave the LAN side of it 64.183.221.241 /
29 and the WAN side to the 192.168.0.0 network. And the Cisco E1 is
64.183.221.242 /29, GW .241 This duplicates the addressing on both
sides of the router at the client's site.

And Cisco E0 is 200.200.200.1 and I have a laptop on that subnet. The
laptop will now ping pravda.ru or lemonde.fr and get a reply.

The only thing that bothers me though, is that I had it working this
way last week (though not with the config changes Merv suggested) on
the 2514 and also on a 2621 for a backup, and they pinged all the way
through... and when I took them to Dallas and set them up with
identical addressing, with no change at all, they would not route
through.

I"m hoping Merv's fix will do the trick, and I wouldn't have found out
if not for you reminding me about the private addressing, Doan.

Thanks to both of you.

Bob W.
