I have three Zentyal 3.5 boxes, two of which are gateways on two different networks.
I eventually plan on linking the different networks/sites using Zentyal-to-Zentyal PPTP VPN or perhaps using LPT2/IPSec.
I have made configuration backups online before I do anything rash, and after some experimentation with the VPN module, I decided to do a restore on both boxes to pre-VPN configuration state. Worked great, love the free feature, but would be nice to have a least a week archive in case you miss something overnight.
Anyway, every time I have rebooted the two gateways after the restores my local area machines lose internet connectivity.
Everything else still works, samba shares, e-mail, but not web browsing. So I restore my backup from online and boom everything is back online and working properly until the next reboot or power outage.
Any clues would be appreciated, I am perplexed and can find nothing on Google relating to this peculiar issue.
Thank You,
Mr. Thomas
