Hi Phillipe,

That's very interesting; do you have any packet filters for PPTP on the ISA?
Was there already a VPN conndection from that client?
Do you have traces of this behavior?
Can you include your isainfo (http://isatools.org/isainfo.zip)?

Re: FP1; many folks have tried it and are very happy with it. Was there something in particular that you were curious about?

Hi all,
In our lab, we're testing ISA server. We try to use web publishing, it seems to work except when a client (supposed to come from the Internet) connects to ISA with port 1723 (client side) on port 80 (server side). In this case, the TCP packet coming from the client is as:
client:1723 to server:80
But the answer of ISA is
server:1025 to client:1723
This answering packet is then blocked by the built-in firewall.
Any idea ?
Any feedback about the Feature Pack ?
