SLOOOW Easy VPN client....

Hi guys,

     Just setup a Cisco 2821 acting as the easy vpn server.  All good, however, the easy vpn client, say for example doing a speedtest, is REALLY slow.

For example, both the client and server have 100M / 5M connections and doing some local speed tests thru the isp, on the client side we are seeing 4M/2M??????  We have very few vpn clients right now, so I can't see the Cisco 2821 being overloaded.

Any ideas for tuning?

I have tried messing with the mtu, adjust-mss settings on the wan port on the 2821, but, no real changes?

Thanks for everyone's time.

Hello Jason,

When there are latency issues over a VPN connection, verify the following in order to resolve this:

  1. Verify if the MSS of the packet can be reduced further.
  2. If IPsec/tcp is used instead of IPsec/udp, then configure preserve-vpn-flow.
  3. Re-load the VPN server box.

Let us know if you could perform them and post the result,

Regards
