watchguard firewall remote office vpn stopped working

we have 2 watchguard firewalls (XTM 2_ devices) at either end of a VPN that others had set up several years ago and has been working fine all that time. I am now backing up remote machines to the home office, so VPN is seeing lots more data.

a couple times now over the last couple months we have the problem that you can't get across the VPN. I really don't know watchguard boxes to see where to look for troubleshooting.

I rebooted the remote office box and that didn't restore the connection.  Waiting to reboot the home office box (see
http://www.experts-exchange.com/Hardware/Networking_Hardware/Firewalls/Q_28411381.html

I can't get into that box right now).

As in previous times, rebooting the home office box likely will restores things.

Any idea where to start to troubleshoot this? I don't know the watchguard interface and don't really know these more powerful firewalls in general.

I would like to just replace the boxes - 1 has expired live security, the other's live security is months from expiring - that's their support, right? I called them about this a month ago and they took days to call me back and defended the turn around time. I had rebooted the boxes and things were working and I wasn't on site, so I didn't pursue things.

any advice?  what's a good / easy to admin box?

As I mentioned in the other question, reboot might indeed be the only option here ... If you're looking for a nice replacement, look into SonicWall I'd say ...
