I will try it again tommorw and copy the configs.
Basically here's my setup. I have three routers in a frame cloud,
R1 R2 and R3 sharing 10.x.x.x. and running ospf fine. I enable nat on
the serial interface on R3 to translate to 64.x.x.x.
I make that interface the outside, and the ethernet the inside. My
ospf adj goes away , and when I debug IP ospf packet on R!, I see the
hellos being sourced by the nat address from R3, and the local router
rejecting them because they don't shre the same network

Please post your configs, I have used nat with ospf before and had no
problems. There are some issues with DLSW and NAT but it will work.

Subject: fun with nat
I've been playing with nat in my test lab, and have found that it
wreaks havoc with ospf. I haven't tried any of the DV protocols yet.
Has anyone tried?
My plan was to do DLSW through NAT but I can't apply NAT, at least
with OSPF.
How do you guys do DLSW through NAT? I mean, how do you "route" to
the routers running NAT?
Static's, RIP,etc.? How about tunnels. I know from real life that
PPTP and L2TP won't run through PAT, which is actually what I'm doing.
OSPF won't set up adj at all because the hellos are sourced form a
network that is not local to the net. (the NAT address). I imaginef
EIGRP will have the same problem.
I guess what I am asking is where and how do you place NAT in your
nets to test how various scenarios work?
Thanks!
