I tried reducing my network load to try and identify when the Edge X falls over. It's unusably slow at 600 concurrent connections, 5k pps, 1.6Mbit bandwidth usage. Details below:

My network:
The Edge X is exclusively used to firewall a single server in my Data Center. I don't have any LAN users web browsing, or any other traffic through the Edge X. There are no VPN users either.

Edge X has single WAN and LAN interfaces defined. WAN is ethernet with public, and is connected to my Cisco router. Server is on LAN interface.

WAN is 2Mbit pipe with peak usage of ~1.6Mbit. I have a peak of 600 concurrent connections. Entire traffic through the firewall peaks at 4800 packets per second. In this situation, the Edge X web gui becomes very slow (even when I connect from the LAN), and my application lag increases until my users start complaining!


Rules in use:
One "Allow and forward" rule defined on WAN to forward a single tcp port from WAN clients to the server in the LAN.

NAT on LAN interface for packets destined to my server. Server does not use Edge X as default gateway, so I NAT all server connections using LAN IP of the Edge X. Note that by design, NAT is not defined on WAN.

Only these basic firewall rules are in place. I don't have AV/SPAM or VPN running as I don't even have a license to activate these features.


As for the suggestions of using a UTM-1, can you please suggest if the UTM-1 270 is capable of satisfying my load/requirement? Thanks!
