9.2.7. PPTP Roaming Clients
3. Define a User Authentication Rule, this is almost identical to L2TP:
Agent
PPP
4. Now set up the IP rules in the IP rule set:
Action
Allow
NAT
As described for L2TP, the NAT rule lets the clients access the public Internet via the NetDefend
Firewall.
5. Set up the client. For Windows XP, the procedure is exactly as described for L2TP above but
without entering the pre-shared key.
