here is my logs. is it error? it just say "ignored". didnt it work?

I can connect to the samba of the vpn server only. In the Lan, there are some WinXp and a Linux with samba. I can see all them via samba client of the VPN server. but I can't access them and can't ping all others. Only the VPN server I can ping.

Please advise how to configure the VPN server or others in order to access the samba of another linux.


Thank you

have u inserted a iptables rule in vpn server box? like:
iptables -t nat -A POSTROUTING -s 192.168.0.0 -j SNAT --to ip_of_local_interface

have u inserted a iptables rule in vpn server box ? like:
iptables -t nat -A POSTROUTING -s 192.168.0.0 -j SNAT --to ip_of_local_interface

I don't have iptable installed.

Should I install it and configure it?


Thanks

r u sure? iptables must exist. as i understand u arent root. so try:
/sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0 -j SNAT --to ip_of_local_interface

thanks

VPN uses GRE, which requires ip_gre module to be loaded. Could this be the problem?

I am also having the same problem. In addition to that, when i connect to the pptpd, the system crashes - i loose all networking and console.
ppp-2.4.1 and pptpd-1.1.4, without using any of the ms features.

brettcave, if u install poptop to rh 8-9, u cat get the rpm packets including kernel-mppe, from http://www.spenneberg.org/VPN/
it works great.
