Are you looking for a way to control which outgoing port ssh uses?
Yes, this is what I want. For example, on a remote ACL you may have your
filters based on:
- destination ip
- destination port
- source ip
I was thinking I could add "source port" to that list..but then , on the
client side, I'd have to specify local binding port.
Irrespectively of its security merits I'm just curious if it's possible at all
(with ssh or any other net tool).
If you want to learn a little about iptables you can just do SNAT to
control the IP and port.
iptables -A POSTROUTING -t nat -p tcp -d 1.2.3.4 --dport ssh \
-j SNAT --to-source 4.3.2.1:24702
That is, if the destination IP is 1.2.3.4 and the destination port is
ssh (22), change the source IP to 4.3.2.1 port 24702
Requires static IP.
