Cisco PIX- PIX VPN Tunnel

dasgill

Dear Experts,

We have a PIX-PIX VPN tunnel accross the internet between our Hong Kong (HK) and Manchester Offices. HK has a Cisco PIX 506E and Manchester has a Cisco 520 PIX. HK has a 512K connection internet and Manchester has a 2Mb internet connection. In a sense there is a 512K VPN connection between HK and Manchester.

The users in HK are complaining that the link is slow. We are proposing to upgrade the internet link in HK from 512K to 2Mb. This will make it a 2 Mb VPN conection between the 2 sites.

Is this possible or do you envisage any issues?

Kind regards

Are you doing any bandwidth monitoring currently - areyou sure bandwidth is the problem?

Are the connections symmetric? Some DSL and cable connections are assymetric, which changes the way you need to think about them.

As for the hardware - you should be perfectly fine handling a 2Mb vpn connection between those PIXes

Our experience with connectivity to China (from the US in this case) is that the bandwidth is not the issue. through many months of monitoring and route adjusting we found the problem is related to bottlenecks at provider aggregation points. Performance up to these points in either direction is acceptable - once crossed we see (at worst) 4+ hops with 25%+ packet loss and response times between 400ms and 2700ms.
