I have an arp problem I am configuring PPTP (poptop) (I know its not supposed to be secure enough but my friend wants to use it) I have a firewall Vpn client -eth0- (vpn) -firewall- eth1--> local lan 192.168.0 \- wlan0 --> wireless local lan 192.168.1 The problem is when the vpn is establish and the wlan0 is up and running the Arp table shows the wlan0 interface for the vpn and I cannot ping thru on the vpn. When I shut off the wlan0 the arp table is correct and I can ping from the client to the local lan. Has anyone run into this problem with a fix????
