Yes, we have the same Problem. After Migration from 77.30 to 80.30 we have "TCP-Retransmission Drops"
One of our internal web application working for years without issues. After this Migration the application is stopped working, no changes were made in the application.
We found…. http://[ip-address]/wording/ is working
http://[ip-address]/wording/?search=word1+word2&initSearch=2&core= is not working
If we delete the "+" sign, it is working. IT seems Checkpoint 80.30 don't like "+" signs.
We don´t use application filtering or other blades - only IPS.
Workaround: We fixed the issue by making an exception in the IPS.
Any idea what's wrong?
