Notes: Mosh IPTable Rules

I recently picked up a Note 3 and with the larger screen I found myself want to use it for shelling in to my machines. So I started playing with Mosh on one of my boxes. I (like hopefully most of you) set strick IPTable rules to keep things locked down as much as possible. I quickly found that (obviously) things weren't working due to this.

To make things work, I added this line to /etc/sysconfig/iptables:

-A INPUT -p udp -m udp --dport 60001:61000 -j ACCEPT

Here's the diff:

diff --git a/tmp/iptables.old b/etc/sysconfig/iptables
index d4229ca..b950f1f 100644
--- a/tmp/iptables.old
+++ b/etc/sysconfig/iptables

 -A INPUT -j REJECT --reject-with icmp-host-prohibited 
 -A FORWARD -j REJECT --reject-with icmp-host-prohibited 

Once you've added the line, simply restart IPTables like so:

sudo /etc/init.d/iptables condrestart
