I recently had reason to query whether XNet was blocking port 445 (they were) and in the course of answering my question XNet sent me the following comprehensive list of all ports blocked.  I thought it might be useful for reference purposes :)  It is not possible to unblock ports on a per-user basis (with the exception of port 25 - see below).  BTW, I emailed them today (sat avo) and got a reply within 30min!  10 points for XNet service!!


Hi Sam,

Yes, 445 is blocked for security reasons.

The following ports are blocked on the Xnet Network TCP/UDP. A static
route can be added via www.xnet.co.nz/staticip to remove the port 25 block.

None of the other ports will be unblocked as they are blocked due to
security holes and possible exploitation.


tcp any any eq 25

tcp any any eq 135
udp any any eq 135

tcp any any eq 137
udp any any eq 137

tcp any any eq 139
udp any any eq 139

tcp any any eq 445

tcp any any eq 593

tcp any any eq 4444

tcp any any eq 3997

tcp any any eq 2745


I apologise for any inconvenience this may cause, however we need to
consider the security of the network for our customers.

Best regards,

Pretty sensible list of ports to be blocked.

It's a pity they don't provide for a a 'Power Users' group for those of us who know what they're doing & are prepared to take the risk. Hell, I'd sign a waiver to have full access!

Yeah but why do you need port 445 for? It's normally used for SMB on a local network.

when I was at a certian second rate ISP there was someone who had 137/139 open on a dsl connection so that they could print to it. One day telecom blocked it. He was not happy and didnt seem to see that having it exposed was a problem.

No more insecure than FTP!
