The only times I've seen VPN tunnels hang for no apparent reason was when 
there was an MTU mismatch. From years ago: DSL requires smaller MTU. Most 
recently and currently, my ISP (Comcast) tells me to use an MTU of 576 (via 
DHCP); but it keeps using MTU of 1500. I couldn't figure what was wrong until 
I told my DHCP client to ignore that MTU directive. No VPN trouble since then. 
This is probably unrelated to your troubles, though.
