When I replace the Internet router with a new router configured with the same Ethernet IP's I can't talk to anyone on the subnet. If I roll the old router back on-line all is well. I cleared xlate and arp and even did a reboot. If I leave the old router on-line I can bring the new router on-line in the subnet with a different IP and see all hosts in the (Outside PIX) subnet. Never had this problem before. Any ideas? IOS is 6.3.
