Subject: Cisco support multiple pptp (GRE) Channels ?

Hey,

	Does anyone know if a Cisco firewall can support multiple PPTP (GRE) 
channels from internal clients to a single external server ?

--snip--
Right now the PPTP server is on the public network and it is working 
correctly for connections from all clients. We have a private network 
from behind a firewall, let's call it firewall A. A single client from 
behind firewall A can connect with out a problem, however if a second 
client tries to connect from behind firewall A it looks like firewall A 
does not forward the PPP LCP packets.

Am I correct that mutliple GRE (proto 47) tunnels would be a problem 
when the clients have the same IP address ?
