Hi Dennis, 1. Protocol rules shouldn't include the "Server" variations; they don't help 2. The packet filters should look something like: "SMTP" TCP Outbound remote port 25 local port any "POP3" TCP Outbound remote port 110 local port any "DNS Q" UDP Send-Receive remote port 53 local port any ..not sure what the "1080" port is for; though it's usually either a web proxy or SOCKS.

I'm quite new to ISA server, but I want to make it up and working :o) I'm having problems with my internal e-mail server (MDaemon) installed on the same computer. I do not need it to be accessible from the Internet, but Internal users should be able to send/receive both internal and external messages. What have I done: 1) Created protocol rules for DNS, POP3, POP3 Server, SMTP, SMTP Server. 2) Created IP Packet filters allowing communication on 25,110 and 1080 ports of ISA box. But I still can't make mail server working... In MDaemon's log I can see "Winsock error 10065: The host is unreachable. Are You connected to network?" DNS is working nice. I can surf the web, but mail... :o(((( By the way, ICQ also not working. What did I forgot? Should I mention something else? -- Best regards, klim ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
