In the office the other day we had a small lighting storm that knocked power out for 30 seconds. All the servers were attached to UPS's, and the networking equipment were attached to surge protectors. When the storm dissipated and power was returned everything worked great but the cable modem is acting all screwy. Our internet service is Optimum Online Ultra with 100mbit download / 15 mbit upload and the modem is the Motorola SB6120. It was connected to our PFsense box since January and we had no problems, since this storm the modem wont connect to our PFsense box.
The PFsense box -
2.4 GHz Core 2 Duo Processor
4 Gig of Memory
80 SATA HD
4 PCI Intel 1000GT Gigabit adapters
Kinda overkill but it was made out of spare parts I had lying around
Steps I tried
1. Did the obligatory unplug modem for 30 seconds and plugged it back in - Nothing
2. Replaced our PFsense Router with our older Linksys RV082 Router to see if it may be the PFsense box and that worked ! So I initially thought it was our PFsense box and took it out of the rack so I can troubleshoot it the next day.
3. The next day I went through the box and checked to see if anything went wrong. I put together a small inner network where I could set up the PFsense box and check if it worked and it Did! It pulled a WAN IP and corresponding info from my DHCP/DNS Server and its internal DHCP server pushed an address to the desktop I hooked to the test network. It worked fine and didnt give me any problems for the 6 hours I had it set up.
So I decided to put it back into our environment and check to see if it would work and it didn't. I did manage to get it work for a little by spoofing the MAC address of the older Linksys router but didn't work for long. I hooked the Linksys router back up and it worked. I did notice the following: The cable modem works fine with a 100 mbit full duplex connection to network but when it goes the 1 gbit connection of the PFsense to the network it doesn't work. I think its the cable modem but I don't really know !
Any help from the fine fellows of AT would be greatly appreciated.
