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

I don't have iptable installed.

Should I install it and configure it?


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.
