iCal server 2 - Access from home and on the move

Hello, We are running a Snow Leopard Server and using iCal within the LAN. All MacBook clients can connect their local iCal application to the server and achieve bidirectional updates via the native iCal application or using their web browser accessing their own page/cal on the Mac server.

I need to access the ical server from home and on the move, Is it a case of port forwarding to the server? I opened the ical ports and use the registered domain name/external ipaddress, I can reach the web server, I can establish a VPN, I can even access group and individual group cals from the web browser, I can't update using the iCal application on my macbook whilst on the move. Any ideas?

Many Thanks.

An individual user with a served calendar (iCalServer setup for Authentication->Any Method, HTTP port 8008) will be served on port 8008 if authentication can be achieved.

So for a Kerberos authentication port 88 open will allow authentication to proceed and service on port 8008. Similarly for other methods.

However to achieve delegation (or use locations and resources) does the client have to be bound to OD master LDAP database? If so then port 389 would need to be open. Similarly for secure setup ports 8443 (ical) and 636 (LDAP ssl) are required.
