Multiple VPN connecions

[Fernando Simonacci <fernando.simonacci () webred it>]

Greetings list,

I'm just dealing with a silly problem but that seems to me with no 
solution. Here is the scenario:


[ServerFarm(Cisco VPN3000)]<->Internet<->Router<->[pc.(Vpn Client sw)]


The company I work for, gives access to it's services only to remote 
pc.s via Cisco VPN client sw.

Everything works fine only if the remote router is a Cisco device (let's 
say 827,  837,  1720 or greater models) or remote pc.s are calling 
through a generic Internet connection (ADSL, Dialup, etc.).
In such situations where the remote router is not a Cisco device, it 
seems that only a single VPN connection is allowed by the router itself  
and every new VPN connection causes the existing one to be dropped. I 
guess that the router drops the active VPN connection for a kind of 
security reason, related to the discovery of  a routing modification due 
to the request of a new VPN connection, but I can't figure out how to 
work around the problem.

Having a single remote pc. working a time is not a good solution, 
neither is the whole substitution of remote routers with Cisco ones'  :-) !

Does anybody have any suggestion?

Thank you all
- Fernando
