So I picked up a routerboard 750, and I've been having a very interesting issue with it. When I let it grab a DHCP address from my ISP (Cox Communications) I am able to ping out without dropping any packets, and have my connection work w/o any issues. Although when I switch it to a static IP address I am able to receive about 10 responses, and then the ping goes dead for a few minutes, 10 responses, and dead again.
Now for some background on this, I have a Cox Business connectin w/ 2 static IP's. I am running my modem into a second VLAN on my switch (Cisco 2900 XL, no tagging, just a seperate VLAN on the switch.) After the switch, I have it distributed between my Cisco Pix and the routerboard. I have ran this setup w/ several other devices w/o issue, so I'm just wondering why it is an issue and if anyone else here has ran across a similar problem.
Also, just an FYI, I'm starting to think it may be a compatibility issue, since I just read about a verizon customer who had to get verizon to lock his ONT to 100mb full duplex because of a compatibility issue. The only thing I'm truly wondering about is the intermittent ping that I get w/ a static IP behind the cisco switch.
