Hi there,

in the bank network enviroment between 2 sites (first with the clients and the second with the server) we have performance problems with one application. One point which might be the cause of our problem is MTU size. The application is using SSLv3. The WAN link is encrypted by IPSec. What would be the suitable MTU size configured on the router? What is the size of overhead of SSLv3? What we need to add in terms of MTU size when we use SSLv3?

Thanks a lot in advance for the answer.

You need to increase the MSS to more than 812 bytes when using SSLv3. Another way is to change the communication profile ie change the POST.
