I try to explain my problem with my poor english......
I have a small lan (5 Clients win9x) and one windows 2000 server sp3.
The LAN is configured with class ip 192.168.0.x/24 (the clients) and win2k has ip 192.168.0.5/24 and default gateway is 192.168.0.1 ( router zyxel)
I have one router connected to internet with a xDSL connection.
The router (a Zyxel prestige 600) has ip 192.168.0.1, that is the default gateway of my lan.
All client (win9x) can access internet without problem and win2k act as DNS server cache.
On the server win2k i have configured Routing and Remote Access service to allow PPTP connection to dial-in. I configured my router to redirect port 47 UDP and 1723 TCP from external (public ip) to internal IP 192.168.0.5 with option 15 (sua server in zyxel router). With this configuration it' all OK and VPN clients can connect my LAN over Internet with Microsoft VPN adapter.
THE PROBLEM - When a client connect my network trough VPN tunnel my lan show some malfunction:
- The 5 clients (win9x and one win200-pro) have some problem to browse the internal network (seem that there are some problem with NetBios resolution)
- If I try to ping (from internal lan) my win2k server reply with 192.168.0.21 or 192.168.0.22. Seems that the win2k server use the vpn clients ip to connect in internal lan.
I try to change many options in RRAS service, but i have the same problem. I solve the problem eliminating routing in this service, but if i do this, the vpn clients cannot connect any ip in my internal lan.
I hope in a prompt reply because i don't know to solve this problem.
THANK in advance.
