No more than one VPN connection

Q: I'm having a strange problem again whereby my network is only allowing
1 outgoing pptp connection at a time. Im setup like this:

net--netgear router--Internet--firewall--dmz firewall--lan clients.

The lan clients are a mixture of 2000 and XP pro. When have about 50
external pptp services that we need to connect to now and again. When
one internal clinet connects to a remote pptp service the connection
is fine until another internal client connects to another remote pptp
service - at this stage the first clients connection drops.

Can anyone suggest where the problem may lie or suggest any
troubleshooting tips ?

(NOTE: i also host a pptp service but incoming connections are rare.
I don't think the incoming traffic is effected but im not 100% sure).A: It is probably the Netgear router. Many SOHO routers only allow one pptp
connection to be made through them.

Note: the second VPN connection may receive Error 721.
