Citrix may be the gotcha in this mix. It doesn't like its endpoint changing, which could happen here since the gateway is changing. The sessions will likely drop. If the routing to the endpoint changes, then it should stay up. If the server is behind a firewall and the outside IP is changing, they'll complain. And often is a LAN setup that gets pushed to the web, the citrix config doesn't support reconnect, but rather restarts the windows environment.
Usually when people are looking for this kind of a setup, dropping sessions is not acceptable to the management group. The eiop solution Josh suggested should work. Key will be to make sure the customer is not expecting Instant handoff. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Josh Luthman Sent: Wednesday, April 28, 2010 3:46 PM To: Mikrotik discussions Subject: Re: [Mikrotik] Redundant Gateway on Bridged Network That should be very easy to do.
