    Default Port Forwarding 443

    Hello everyone,

    Iím new to Zimbra and need some help setting up web access. Let me start with some back story; we first installed Zimbra on a server outside of our firewall and webmail and the admin console worked great by going to https://mail.mydomain.com and https://mail.mydomain.com:7071. Due to spam problems, we were forced to bring the server back behind a barracuda firewall. Iíve setup port forwarding to the servers internal IP address on our comcast router for ports 443 and 7071 but canít seem to reach server outside of our network. What am I missing? Thanks for any suggestions.

    Hi wsillc,
    Maybe you have one of this problems:
    1.- The port 443 is reserved by the own Barracuda and you can not do a forward of it.
    2.- You did bad the forward of these ports

    Could you please put a screenshot of the NAT?


    Kind regards

    Thanks for the replies, I think I’m one step closer to figuring the problem out. I noticed when I’m outside our network I can connect to our server using https://mail.mydomain.com. Port forwarding must working but I need to configure our local DNS to resolve the internal IP to https://mail.mydomain.com. I will let you know if this solves the problem. I still need to figure how to configure the local DNS records.

    That's called a Split DNS and has been covered many times in the forums and there's even a wiki article that describes it's configuration.
