I suspect my Alix embedded appliance (500 MHz 586 class with 256 MB RAM) is getting maxed out via either heat or traffic. a. Don't have any "active" packages installed - just "Backup" b. Have 11 entries in DNS Forwarder for my internal network c. Doing OpenDNS d. Have a VPN defined although I have only used it once. e. Rejecting UDP port 80 on LAN f. Rejecting TCP 6667 (IIRC), 135 (MS RPC) on LAN g. Rejecting TCP/UDP 445 (SMB/CIFS), 137-139 (NetBIOS) on LAN. My imac and a PC laptop generate a lot of 137 traffic that gets blocked. h. Doing Vonage VOIP traffic shaping i. I use the Internet mainly via a D-Link N wifi router connected to a HP Procurve switch. The firewall is also connected to that switch.
During heavy (2 people streaming) the network(Internet) keeps cutting out. For the longest time, I thought it was either the Verizon DSL service or my in-house phone wiring. Although the wiring is crappy, I have pared it down to either the HP Procurve 24 port switch or the pfsense firewall. I called Verizon last night and plugged a laptop directly into the modem bypassing the switch and the firewall while the service was going through on-again, off-again cycles. And voila, the speed picked right up and stayed up and stable during some big-file download tests. So, the question is how do I test the firewall? Mehma
