Hello,
I was hoping to get some quality answers from all you professionals out
there about some ports I have been asked to open up on our firewall.
We have a Watchguard Firebox II firewall connected to the Internet
(External), the corporate LAN (Trusted) and our DMZ (Optional) which is
locked down tight except for only the essential ports to allow the servers
to do their job.
The ports I have been asked to open are:
1494 - ICA
1604 - ICABrowser
139 - Netbios Session Service
The is to allow a Citrix server in our DMZ to communicate back through to
our corporate LAN (Trusted) to another Citrix server.
Can you tell me if I'm about to open up a can of worms, or am I ok to open
up these 3 ports?
What is ICA and ICABrowser anyway? I asume its a Citrix related service?
Please advise
Regards
Simon
