I'm configuring a dd-wrt router to allow access via VPN to a remote desktop server. The router will sit behind another router providing NAT. I'm configuring it with a backup 3G mobile broadband link.
My primary concern is maintaining connection to a Citrix server. The land-line connection bounces (alternates between being up and down) sometimes, and the frequent disconnects wreak havoc on the remote desktop session.
Can I configure reliable multipathing over the two WAN connections?
- Is this even possible behind two routers with NAT?
- Will the latency of the 3G connection cause problems?
- Can I maintain enough connection quality to prevent disconnect?
I'm not concerned with a truly 'seamless' failover, if it stutters for thirty seconds and comes back up that's sweet victory. The connection is only shared with one or two machines, and I'd like to get this done on a Linksys WRT54GL.
