SSL VPN Client / Slowperformance

Hello,

we're using UTM 9.004-33 and we connect our outside people via the integrated ssl vpn client to the utm. The user only us RDP-Protocol and the performance of the connection is very slow. When a use type some letters it's appearing seconds later. This is not an issue about the connected servers.

ok how many users? also are you using ssl or ipsec and then tunneling rdp over that? the other side of hte coin is the users's upload connection. then the route between the two. One ore thing is this an appliance or a custom build? if custom need to know cpu/ram/nics..etc etc. if appliance which one?

Agreed with William - this feels like a NIC problem. The SSL VPN is much faster if configured with UDP instead of TCP, but this isn't causing the slowness you describe.

Cheers - Bob

Hi To all,

yesterday evening we solved the problem. We changed, the settings of the used port, then we change from tcp to udp. And at the end we changed everything as it was before the made changes. Now our lines are running great.

Hi,
we changed under Remote Access->SSL->Settings the field protocol to udp, then we change the port to 1443, and at the end of our tests we discharged all changes.

This worked for us
