ISA On Win2K/SP4, firewall/SNAT client running Win2K/SP4 behind it. Client can browse the web, do FTP, whatever. Web proxy client stuff is off, IE uses the firewall client to browse the web. DNS is running on the ISA box as a forwarder only, all LAN systems use the ISA for DNS. I enabled (Microsoft) VPN on the client to connect to a Microsoft VPN server out on the internet. As soon as it activates, browsing and etc is slow on the client and the ISA server cannot browse the web. ISA server Event Log also shows this: " Server publishing rule [DNS Query Server] that maps 10.10.2.1:53 UDP to 220.127.116.11:53 for protocol [DNS Query Server] failed because the port on the external interface is being used by another application. The Firewall service failed to bind socket for the server on the firewall since another process is using the same port. Check for any other process using the same port and terminate if necessary. " " Server publishing rule [DNS Zone Transfer] that maps 10.10.2.1:53 TCP to 18.104.22.168:53 for protocol [DNS Zone Transfer Server] failed because the port on the external interface is being used by another application. The Firewall service failed to bind socket for the server on the firewall since another process is using the same port. Check for any other process using the same port and terminate if necessary. " 1. How do I get my VPN client to play nice and not take over the ISA?. 2. How can an internal client take over the firewall service, when it had a lock on that port initially? Thanks.
