After migrating to a new datacenter, with new public IP set, I had to add
static ARP antry and static MAC address table entry to get this working as suggested by many articals.
This will work for some time, but strangely router loose the above line from running config, and I can see the line in startup config.
But sh ip nat translation show many translations to 10.y.yyy.18 and email working OK, but last time we had spend much time to solve the issue after some days it stop using .18(virtual address). This happen again yesterday and still working but I am waiting for more trouble
I notised this NAT statement reappear after clearing the IP NAT Tranlations. It may be due to resource limitation in the router or NAT time out issue, if any one know how to the dynamic NAt time out in a 2188 with "extendable" keywork included in the IP NAT statement
Hi, I am waiting to upgrade this 2811 to 2851, for that reason I didn't pursue this any further, but clear ip nat tra * would reapear the NAt translation line for a while, depending on the NAT workload it disaprear accordingly.
My guess, it is bug, and may the workaround is reduce the NAT tranalation time out. I don't know how to do that.
