Hi Johnny,
Perfect! That is the exact information I needed.
If the vendor is correct about the protocol (which is a 50/50 chance), then
what you need to do:
1. Create the protocol definitions:
- TCP 4262 inbound
- TCP 4711 inbound
- UDP 4672 inbound
2. Create the protocol rules, each protocol rule using one of the new Protocol
Definitions you created. The external addess is on the external interface of
the ISA Server firewall, and the internal address is the address of the Windows
XP client on the internal network.
That's all you need to do. When an external user connects to the external
address of the ISA Server firewall on TCP ports 4262/4711 and UDP port 4672,
those packets will be forwarded to the Windows XP machine on the internal
network.
HTH,
Tom

OK Thomas, I´ll clarify.
I have one ISA server SP1 in integrated mode. 2 NICs are installed in this
server - 1 for the external network (the Internet) and 1 for the internal
network (192.168.x.x).
The XP Pro client is installed on the internal network.
I am not using DHCP.
It is on the XP Pro client an application exist which has to be accessible
by external users (Internet) and according to the application maker, TCP
ports 4262, 4711 and UDP port 4672 have to be forwarded (the incoming
direction) to the client since users on the Internet will otherwise not
see the client. They will only see the servers IP.
I think I am clear about that I have to create some types of packet
filters but I am not sure on how to configure these.
Thanks,
Johny Lundgren
