Hello again,
I am using PPTP VPN (npppd) and it works as expected on windows clients - traffic to the "LAN behind that VPNgateway" is going through VPNgateway. The "rest" is going through clients' gateway - DO NOT "use default gateway on remote network".
I have been playing around with iked.conf, pf.conf and ipsec.conf - still cannot get it working in this manner.
I do not want to use OpenIKED as a internet gateway, VPN is needed only to access "LAN behind that VPNgateway".
Could someone please help me with this problem? Christmas is coming...
Many thanks!
