I am running into issues attempting to mount a folder on a CentOS server, which was shared from another CentOS server.
I set it up following option two on https://www.howtogeek.com/176471/how-to-share-files-between-windows-and-linux/
I managed to mount the share on Windows just fine, so I don't think I have a firewall issue on the hosting server.
I am attempting to mount this with autofs, this is my config:
winbox -fstype=cifs,rw,noperm,user=USERNAME,pass=PASSWORD ://MYIPADDRESS/Share
When I try to cd into the relevant folder, I get the following in my logs:

The root of the issue from what I can tell being:
>> Unable to find suitable address.
When I tried to mount it directly, I am getting the same issue. However nothing I can find is pointing me in the right direction.
I can ping the IP address just fine, this is also not a local server.
I think I have actually narrowed down the issue to my firewall on the host server. I have the following in my iptables:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 445 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 445 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 139 -j ACCEPT
If I disable iptables things work just fine, so I must be missing something above.
