iFolder3 running on SLES. Everything works just fine inside our firewall. client can login and sync with ifolder3 client. however outside the firewall the ifolder3 client can login but cannot sync. when i try to manually sync the folder the message says "server unavailable".

We use a Cisco ASA firewall and NAT an ip address with ports 80 and 443 for the ifolder3 server.

The client works just fine when using VPN also.
