Do I need to open port 980 (iptables) on my office computer? In my opinion - no. For outgoing traffic nothing is blocked.
I tried it and had no success as expected.
Then I had the idea to look into /var/log/iptables/current and saw: every try from office to home ended up into iptables' chain denylog!
So I tried 1st entering manually (again: aa.bb.cc.dd = office PC)
[root@sme ~]# iptables -A InboundTCP_22934 -s aa.bb.cc.dd -p tcp -m tcp --dport 980 -j ACCEPT
Unfortunatly no success. 2nd I deleted that rule an tried another:
[root@sme ~]# iptables -A InboundTCP_22934 -s aa.bb.cc.dd -p tcp -m tcp --sport 980 -j ACCEPT
And ... drumroll please ... it worked!!!
Seems to be a bug: If one enters a host into Remote Management, it should be appended to iptables' rules - but will NOT. Shall I report a bug?
