RDP Freezes with SecureXL Enabled

HenrikJ — Thu, 01 Jul 2021 09:21:26 GMT

Hello!

We are running a Maestro Solution with a weird issue.

Solution consists if a single MHO140, 1 SGT consisting of three 6600 gateways.

What we've seen is that RDP intermittently freezes.
When I mean intermittently, I mean that a server does get the issue, it persists for a while regardless of new sessions.

When checking TCP Dumps, fw monitor etc, we see it complain about bad packet length (udp seems to report a larger length than IP).

Also, this is completely gone if we disable SecureXL.

Has anyone else had this issue?

Best to take it with TAC.

Yes, I suspected as much.
But always nice to have it confirmed, so it's not a commonly known problem.

Thank you 🙂

Not as you described. There was an issue with RDP over VPN, outlined in sk173124. Check if it is your case.
