@stephenw10 said in Poor performance over IPsec but not Internet:
In the Phase 1 advanced options settings set 'NAT Traversal' to Force to test ESP specific throttling. Only one end needs to set that.
I know I'm necroing a 3+ year old thread, but holy crap this was exactly what I needed here.
My main office is on a 500/500 fiber connection, and we have a remote office on coaxial cable running 500/10, and over the VPN I could barely get 20 Mbps, but over the internet I could get the full 500 Mbps.
I tried setting the 'NAT Traversal' to 'Force' on our main office, and forced an IPSEC reconnection and now I'm getting about 480ish Mbps over the VPN (internet is around 511 Mbps).
THANK YOU THANK YOU THANK YOU
Again, sorry about the thread necroing :(
