Most of the time this is due to the capabilities of the user's router.
Many will only allow a single concurrent VPN connection. Generally a
google search using the router make and model along with "vpn" will turn
up specifics on the router in question, and if there are any

I'm not sure I understand your diagram correctly but we have lots of
users connecting from home using Linksys and DLink routers. We haven't
had any problems with the VPN3K dropping connections.

Subject: Multiple VPN connecions
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
