[vpn-help] MULTIPLE VPN tunnels - simultaneous connections

Hi Kevin,  

No overlapping subnets and no "tunnel all" either.  But!!! It's working now!

I tried once again behind a different router and ISP (was testing at work over ADSL, then tested again using SAME laptop at home) and I was totally able to connect to both tunnels and send traffic down them simultaneously.  

Not sure why really.

Hi Christina,

Do you by any chance have overlapping destination subnets?  Or maybe
one of the VPNs is set to tunnel all?

Regarding the previous VPN clients, I know that Shrew and
NetScreen-Remote do not co-exist well - check to make sure that you do
not have the Deterministic Network Enhancer installed in the network
adapter properties.
