Application trouble over site-site vpn link

I have some problems with a program that won't initiate over a vpn link. Users on the 192.168.99.0 side, starts the program client. The client then contacts its database on 192.169.98.12, to load the program. The user credentials, clearly gets checked, as a wrongful password is denied. The client tries to load the program, but hangs.

Heres the log on the 192.168.98.0 side:

Everything else, communication wise works flawlessly on this link.

Any ideas ??

All help appreciated!

Re: Application trouble over site-site vpn link

Sorry for the bump, but surely someone must have something clever to say about this log?

There are three lines here, that i think might be the source for the "Deny TCP (no connection)..." entries:
