Remote SSL VPN Users cant reach port 4443/4444 on their browser

BigShark

Some Remote VPN users cant reach Admin Page and User Portal on both 4444/4443 respectively but pings and telnet work on those ports from the same system. Could it be public IP related problem?

    Things to consider because you said the problem only affects some users.

    Some remote locations may have their own web filter systems, and have them configured to block nonstandard ports

    Some PC-based security products do web filtering, so you need to poke around in the administrative interface to learn what it is configured to do.

    Many thanks Foster,

    We have worked on the PC-based filtering rules by disabling windows firewall and other web filtering tools the issue status remained the same. I expect at least the login page to appear since they are able to telnet into those ports. We have changed browsers and other but could it be a bud in the firewall since TCP traffic isnt working for some users ?

    Show us a line from the Firewall log file (not the Live Log) where dstport="4444" is blocked.  Do the same for the other port.
