Title: Outgoing ports closed
Post by: bvdam on December 18, 2002, 05:26:23 PM

I am having a problem with that all my outgoing ports are closed except port 80.

My ipchains looks like this:

Chain output (policy ACCEPT):
target     prot opt     source                destination           ports
icmpOut    icmp ------  0.0.0.0/0            0.0.0.0/0             * ->   *

Where should i look?

What do IP Masquerading entries show? It seems as they show all the connections that fail.

Thanks

I have tried the "Port Opening" contrib to SME. It adds this line:

ACCEPT tcp !y---- 212.55.51.74 0.0.0.0/0 portno -> *

But I still can't get a connection through the port.

I solved the problem. It worked when I used another nic rather than the embedded Intel 1000 with the driver from http://myezserver.com/downloads/mitel/contrib/Intel/e1000-4.3.15-sme55.i386.rpm

I'll just have to wait for a newer driver. Perhaps it will work.
