Slow site to site VPN

[ldutchman]

Could you help me and look these running configs over for improvements

This is my first attempt (successful?)at ASA configuration

Everything seems to work great except the tunnel is only transferring at 220-230Kbps

ASA #1 is a 5510 8.2(2)
Inside 10.0.0.0/24
Ouside Bonded T1 speed tests good consistent @ 2-2.5Mbps

ASA #2 is a 5505 8.2(2)
Inside 10.0.6.0/24
Outside Fiber speed tests good @ 1Mbps up and 10 Mbps down

Tested VPN afterhours with no users on network


ASA #1 5510

I would disable any Inspect Maps to start with.

Also check the processor load on the ASA, perhaps something is bogging it down causing the VPN to run slowly - as Encryption can be quite a load on any system.

Also, unplug all devices off the network and check with say just your laptop and also on other device on the other end and transfer a file via FTP across the tunnel.

Another point, some ISPs throttle encrypted traffic as they assume all encrypted traffic is Bit Torrent traffic (torrent transfers are often encrypted these days to stop people like MPAA etc sniffing the traffic.

ACSS - SME

another thought, the NTE that connects your fibre, its it set to 10Mbit half duplex?

if its managed by the ISP ask them to check it, and then match it on the ASA
