SSL connection via port 443 too slow

I have Cisco 837 router/firewall installed with Microsoft SBS 2000 running on Dell server with two NICs.

On the router, I have enabled SSL 443/tcp port and created a static entry in the NAT table specifying the external (WAN IP) and an internal IP (IP of the external NIC of the server) and specified a port number.

The access via https works very fast on the internal LAN, but very slow initial connection time from external world. (~ 3-4 minutes)

Anything in the router configuration that can help to speed this up?

It seems the access is slower from PCs running Windows 2000 than PCs running XP Professional.

Thank you

Murat

Re: SSL connection via port 443 too slow

Hi,

What can you do on a router? You can define a static for the translation and an access-list to permit the traffic. Thats all.

You first need to make sure your router is not reaching 100% of the link capacity or the performance.

I doubt that is the case though

It seems to me an issue with the server. Mostly windows servers tries to communicate with the first IP address. YOu can check this by capturing the network traffic. If that is the case, it could cause re-transmissions etc.

Thanks

Nadeem
