Subject RE: How to create a network offering without firewall?
Date Thu, 27 Jun 2013 10:40:51 GMT
I had this issue too some days ago. I solved it by logging into the Virtual Router over ssh
and adding this rule to the Firewall: 

iptables -A FW_OUTBOUND -j ACCEPT

I hope this helps.

Regards

Is internet accessible from from router ?
If it is accessible please send router iptables rules on pastebin.com
