Issue connecting to HTTPS sites since updating firmware on ISA550W

Good afternoon,

I'm hoping someone may have had same issue or may have a fix for a weird issue I am having with My ISA550.

I have recently updated the firmware on our ISA550W to 1.2.19 and it seems ever since then any connection to a https site takes ages! 

Our config is dual Broadband lines with policy based routing used to route internet traffic over our 2nd line. Even if I turn off the Policy Based Routing internet access is very slow to HTTPS.

I have checked the next hop router by using one of our public IP's on the back of it and all works Ok with no issues, so i can only pinpoint the issue to the ISA.


Any idea's?

I've now rolled back the firmware but issue still there. Accessing sites which are either SSL secured OR have an element that may have SSL content are impossibly slow.

This is driving me nuts!
