Strange WAN connection issue
I am running an OC200 with the ER7206 and trying to connect a new fiber line through Ethernet. It's kinda a long story, sorry.
Starting off today I had four DSLs on WAN1-WAN4, all working fine. There was a new fiber line installed at the location so the absolute first thing I did was to configure my laptop to connect directly to make sure the fiber was good. I connected a cable from the Ethernet output of the fiber converter directly to my laptop and configured the Ethernet port in my laptop to these settings:
IP Address 173.195.163.130
Subnet Mask 255.255.255.248
Gateway 173.195.163.129
VLAN 270
DNS1 8.8.8.8
DNS2 4.2.2.2
Ping 173.165.163.130 = Success
Ping 173.195.163.129 = Success
Ping 8.8.8.8 = Success
Ping website = Success
Speedtest = 420/415
All good! I configure WAN port 4 on the router to those same settings, unplug the end of the Ethernet cable from my laptop and plug it into WAN4, then I run my tests...
Ping 173.165.163.130 = Success
Ping 173.195.163.129 = Fail
Ping 8.8.8.8 = Success
Ping website = Success
Speedtest = 75/1.8
Keep in mind that there are still three active DSL lines on WAN1-3. Lights show no activity on WAN4 or the fiber converter Ethernet port. Weird. Just for grins I try the same thing except I use WAN1 instead of WAN4. Same results.
So now I am getting confused, so I think maybe it has something to do with multiple WANs running so I remove ALL WANs, start from scratch with it on WAN1 as the one and only connection. (and yes, rebooting every time I add or remove a WAN connection)
Ping 173.165.163.130 = Success
Ping 173.195.163.129 = Fail
Ping 8.8.8.8 = Fail
Ping website = Fail
Really puzzled here so I unplug the Ethernet cable from the router, plug it back into my laptop, wait a minute for everyone to talk to each other and run my test again:
Ping 173.165.163.130 = Success
Ping 173.195.163.129 = Success
Ping 8.8.8.8 = Success
Ping website = Success
Speedtest = 418/407
So the fiber and media converter are good. Only difference I can see is maybe MAC Address? So yeah, I unplugged the Ethernet cable from my laptop and plugged it back in the router, went into the settings for WAN1 and changed the MAC address to the same MAC as my laptop.
Ping 173.165.163.130 = Success
Ping 173.195.163.129 = Fail
Ping 8.8.8.8 = Fail
Ping website = Fail
I am at a loss. I know for a fact the internet connection is good, I know for a fact that the Ethernet port and cable are good, I know for a fact that the WAN port on the router is good, I know for a fact that the MAC installed works with the fiber connection, but for some odd reason, all of these known good things do not work TOGETHER. WTH?
Yes, I double and triple checked my settings, including the internet VLAN. It is absolutely acting like the internet VLAN is the issue, and I absolutely make mistakes, but there is no way I made the exact same mistake this many times, and missed it double-checking over and over.
What else could I be missing?
