I'm having trouble getting tcp/ip working once I connect to a machine using PPTP. Here is my network setup. pptp server (freebsd 4.4 - using mpd-netgraph) | | Internet | | Gateway, running ipnat (freebsd 4.3) | | Windows XP Machine. I can connect fine, except I can't really do much from that point on. The server has the ip address 192.168.0.1 and the client has 192.168.0.2. When I try to ping the clients ip address from the server I get this: PING 192.168.0.2 (192.168.0.2): 56 data bytes ping: sendto: Permission denied ping: sendto: Permission denied according to ifconfig, the tunnel seems to be up: ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.0.1 --> 192.168.0.2 netmask 0xffffffff my mpd.conf file looks like: pptp: new -i ng0 pptp pptp set iface disable on-demand set iface enable proxy-arp set iface idle 1800 set bundle disable multilink set link yes acfcomp protocomp set link no pap chap set link enable chap set link keep-alive 10 60 set ipcp yes vjcomp set ipcp ranges 192.168.0.1/32 192.168.0.2/30 set ipcp dns xxx.xxx.xxx.xxx <--- IP address of external interface (yes a dns server is listening) set bundle enable compression set ccp yes mppc set ccp yes mpp-e40 set ccp yes mpp-e128 set ccp yes mpp-stateless and mpd.links: pptp: set link type pptp set pptp self xxx.xxx.xxx.xxx <-- External IP address set pptp enable incoming set pptp disable originate any idea what could be wrong? Is this a nat problem? Blake To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
