Hello
My goals are:
- to use an Win2k server (terminal server) in a lan over the internet (Free=
BSD=20
box with pptpd)
My equipment:
- Win2k server, SP4 (test machine)
- file server
- telnet server
IP: 192.168.1.50
=20
- FreeBSD 4.8
- firewall (all rules works very well, also ftp etc.)
- VPN server (PopTop 1.1.4-b3). I have access from the Internet to
this box over a VPN (=3Dpptp) connection
- ssh server=20
- DynDNS client
IP router side: 192.168.2.2
IP LAN (Win2k server) side: 192.168.1.1
- Router
ADSL Router ZyXel Prestige 642R-I
IP: 192.168.2.3
=20
Here is the schema:
client in FreeBSD Win2k
the Internet Router box server
---- ---- xl1 ---- xl0 ----
| | -------> | | -------> | | --------------> | |
---- ---- ---- ----
(for example:
Win2k, Win9x)
If I start a pptp connect from the client in the internet (they receive an =
ip=20
from 192.168.1.200 to .210), I can ping 192.168.1.1 without problem. Also I=
=20
can ping from my FreeBSD box the remote client and the Win2k server. From t=
he=20
Win2k server I can alway ping the FreeBSD box but not the client in the=20
internet. I also set manualy the arp resolution (MAC adress with ip adress)=
on=20
both side but also no luck.
I started also tcpdump on the FreeBSD box with the following result:
Pings from the client to Win2k server. tcpdump start with options -n -i xl0=
=20
icmp:
23:18:20.217987 192.168.1.206 > 192.168.1.50: icmp: echo request
23:18:21.677929 192.168.1.206 > 192.168.1.50: icmp: echo request
23:18:22.693478 192.168.1.206 > 192.168.1.50: icmp: echo request
23:18:23.709587 192.168.1.206 > 192.168.1.50: icmp: echo request
here the same with options -n -i xl0 arp:
23:20:28.412407 arp who-has 192.168.1.206 tell 192.168.1.50
23:20:29.685452 arp who-has 192.168.1.206 tell 192.168.1.50
23:20:30.701281 arp who-has 192.168.1.206 tell 192.168.1.50
23:20:31.717197 arp who-has 192.168.1.206 tell 192.168.1.50
Pings from the Win2k server to the client. tcpdump started like above (icmp=
):
=2E.. no output
here the same like above (arp)
23:23:24.855173 arp who-has 192.168.1.206 tell 192.168.1.50
23:23:25.923374 arp who-has 192.168.1.206 tell 192.168.1.50
23:23:26.924785 arp who-has 192.168.1.206 tell 192.168.1.50
23:23:27.926212 arp who-has 192.168.1.206 tell 192.168.1.50
I also deactivetd the firewall but also no success.
What the hell is going wrong here?
