Cisco VPN thru a Router performing NAT and a MS ISA firewall
I'm having difficulties getting my Cisco VPN client software to connect to the Access Server. My network configuration is dsl> flowpoint router performing nat> MS ISA server performing firewall and nat.
Thru the ISA server management interface, I have made a protocol definition for udp 500 and udp 10000 for send. I have then made sure that my Access policy has been updated with these protocol definitions. Still no luck.
I have put an Ethereal sniffer in my dmz between the router and the ISA server. I capture the outgoing packets, however I do not capture any return packets from the Access Server (Cisco Pix, I believe. It is a client's site that we would like to use vpn for support purposes.)
