Hey Guys,

I think for some reason I have a weird problem... I have the same IP
address LAN space at 2 locations, identical machines with identical IP
address, I thought I could NAT on both routers to the Inter Site link
IP space but it doesn't work...

10.0.0.0/24 ---- NAT TO 172.16.1.0/24 --- WAN Link----- NAT TO
172.16.1.0/24----10.0.0.0/24

So I have host on both ends with 10.0.0.100/24 same default GW .1 on
both sides and they NAT to 2 different IPs... On the left is
172.16.1.99 and the right it's 172.16.1.100.

Any idea why this doesn't work? I try to ping 172.16.1.100 from the
Left side from the real IP 10.0.0.100 and vice versa but no go.

Thanks,
