[Openswan Users] Road Warriors with same source IP Address

Assuming the remote user's have private IP class C subnet behind their
ISP router/modem/firewall/gateway. Assume each remote user has
configured their PC with the same private IP address. The initial
connections to the VPN server should come from the public IP on the
remote users' routers. Are the remote computers linux or
windows? Is the tunnel for user1 actually going down, or does user1
just get disconnected from corporate resources because the routing
changes? I don't see how two VPN clients could have the same IP
address any more than two LAN clients could.
If you are using openswan on the client in linux from the command line,
I don't think you have an option to configure a virtual adapter (which
would let the remote user have an IP address on the corporate LAN,
therefore abstracting the remote user's real IP.) Openswan in linux
does have gui front ends for the client, but those never worked for me.
Instead I use shrewsoft as the linux gui vpn client, which may
support virtual adapters.
Are you using the strait IKE/IPSEC VPN or are you using LT2P+IPSEC?
