Title: 14.04 Firewall / Port forwarding
Post by: brononius on June 04, 2015, 03:04:10 PM
Is it possible that there's an issue with the port forwarding in the firewall part?
When I add a rule to forward port 10100 towards 192.168.111.100:80 , it's not being added.

It doesn't show up in my iptables either...


Code Select
dcerouter_1044981:~# iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination         

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         

Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination         
MASQUERADE  all  --  192.168.111.0/24    !192.168.111.0/24

Anything is possible, none of the firewall aspects have been tested in 1404 by anyone that I know of.  Alblasco is the man to speak with about any firewall issues.

I think it could be a general problem, I can't add input rules (e.g. ssh ) in the firewall with the latest 2 iso images for 12.04.

Shitty.  Can you make a ticket for Alblasco and reference this thread so he has some background to work with?

J.

ps.  Thanks for testing and reporting!

Sorry for the late response, I was on holiday...

How can I test it for you?

I think Alblasco1702 got this fixed a little earlier today- advanced firewall shows correctly now on my 12.04 install and there's a pending fix available on the next update that should do the rest.  Maybe wait a few days, grab the update and watch the magic?!?

bronius you can test it now when you update and upgrade.
