Personally, I think you will be better off re-pointing your DNS. Here's my logic:
1) By re-pointing DNS, it won't matter where your server is. DNS will point to it. 2) Spanning vlans across a WAN link, especially a slower link, is not a good idea, especially if it is a high-traffic vlan. 3) DNS changes are much simpler to implement.

Would you say that changing IP addresses of server and using bridging (to spread the subnet between the two sides) is a good idea OR modifying the DNS record and setting short timeout on these records is better? (Bridging would have to be based on L3, either GRE tunnel or something else). Thank you for your options. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
