Hi,
I'm unable to figure this one out myself:
I run my UTM at home, behind a cable modem (bridged). So far I've never had any performance issues. Not until my employer set up a VPN server at work to connect to company network using my work-laptop (only via Laptop, not via UTM!!!). It uses Cisco AnyConnect. So the laptop (win7) is situated in my LAN (behind the UTM) and I want to connect to the company net.
Accessing my employers servers via ssh/scp utilizes the maximum bandwidth of my connection (50Mbit/s down, 5 up) (Laptop behind UTM --> outside server). Accessing the same server using the AnyConnect VPN (Laptop behind UTM --> outside server) gives me around 200kbit/s each way.
When I hook up the laptop the the cable modem I get the full bandwidth maximum bandwidth!
I fiddled with the MTU on the Laptop and UTM since I saw some fragmentation messages on the UTM but seeing that the tunnel works flawlessly when circumventing the UTM I figured, I am kinda lost (IMCP was always activated in the UTM).
I ran out of ideas. I tried turning off any security measure. The routing seems fine. I'd really appreciate any help.
kind regards
