SSH Listen on 2 Ports

[john5788]

I have an RT-AC68U running 384.13. Is it possible to run dropbear to listen on 2 ports?

I tried opening a new dropbear process:

# dropbear -p 8022 -a

But I cannot connect to it. Is this an iptables rule I need to add to open 8022 on the router itself so I can connect? netstat shows this port is open, but I cannot connect to it externally.

# netstat -an | grep 8022
tcp 0 0 0.0.0.0:8022 0.0.0.0:* LISTEN
tcp 0 0 :::8022 :::* LISTEN

Nevermind, solved it myself, it was an iptables rule I needed to add.

# iptables -I INPUT -p tcp --dport 8022 -j ACCEPT

And I can now connect.

I'm guessing if I reboot, I lose these changes. How would I go about making these 2 changes permanent on boot?
