Site to Site VPN issue between ASA 5515 and Mcafee (Sidewinders) Firewall.

dharmendra2shah
Level 1
Level 1

We have a site to site VPN with our business partner. Site A is 5515 and site B is mcafee (sidewinders ) firewall.

Randomly the VPN will drop and application will stop working. All applications are running from Site A (where 5515 is residing)

Sometimes the application fails even  though the VPN is up. What is odd is if I reset the VPN on ASA and mcafee side the application will start working after restarting the application.

Also the performance of the application is not good. I tried adjusting the sysopt mss but it did not help.

I am not sure what is wrong with this configuration.

I was wondering if u guys have any advice?

NOTE: The application is TCP based and does a lot of writes on the other side of the VPN (Site B) to the oracle database server.

I was also wondering what is the purpose of timeout tcp-proxy-reassembly 0:01:00

Here is the ASA config.

ASA Version 8.6(1)
