Portforwarding

Spridis · Postby **Spridis** » Tue Feb 20, 2007 3:23 pm

I have tried the Search-button with no success so...

What do I have to do to get Scalix to work behind a firewall (IPCop) with portforwarding?
Is it even possible?
If possible, are there any more ports than 80 and 25 need to be forwarded from the evil internet to gain webaccess and to get emails flowing?

I have registered a FQHN (my Scalix-server hostname) at my ISPs DNS that is pointing to the external IP on my firewall.
What happends if I register the Scalix internal IP (192.168.x.x) in my local DNS-server (IPCop), does this mess something up?

The users need to have full access to the mailserver (outlook etc) when they are at work and only webaccess when they are out of office, no pop or imap to the outside.

Port 25 will allow inbound email.
Port 80 will allow webmail connections.

That should be all you need. We have a number of clients running IPcop in front of Scalix, and it's working quite well. What problems are you seeing?

No problems so far.

what ports do I need to forward for remote scalix-connect users (outlook). These users are on a far end so I need to travese a nat to get to the scalix box.

5729

Keep in mind that in a multi server environment, this will not work.

would it work if I portforwarded the individual user/company each to their respective "home" server?

Not really. Some parts will be fine, but things like delegation can be fairly complex and require DNS resolution between the servers and the desktops to all be correct.

Are you a multi server environment? If yes, I'd advise a VPN for now.

no just asking in case it became that way :-)

Just looking at this thread from a different perspective. We've got Outlook connecting OK via our vpn with 5729 being open, I've read that 5757 is UAL Free/Busy, but I can't find any documentation on this other than being referred to in a few posts. Is it vital to have this open, we've been running for a couple of months with it closed and had a few 'odd' issues with people connecting via our vpn so this may be the cause, but I don't want to open it if it's not actually required.

I've also been through the install and admin docs, but I can't see a list of required ports anywhere, I must be missing something.

we have ~40 people on the outside with just 5729 all using group scheduling and only 5729 forwarded. no weirdness yet :-)
