Iptables enable slave DNS

[kandalf]

I have a server on Linode and I use their DNS servers everytime I create a new domains I add it as slave. I have everything working if the iptables are disabled, but if I enable it the slave dns stop updating.

On Iptabels rules I have this

Code: Select all

ACCEPT     UDP      /DNS     53     0.0.0.0/0

But seems that something is not working. Any tip?

With other server I run this command:

Code: Select all

dig @176.XX.XX.XX domain.pt AXFR

If I have iptables enable I get timeout ("connection timed out; no servers could be reached"), it not I get "Transfer failed.", but I think this transfer failed is not problematic is caused because I have not the ip of the server where I'm running the command on the bind configs.
