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?

TBH from what I see , the Omada range is not that easy to configure with a public IP subnet. Maybe you could post your actual Omada WAN config ?
Who is the ISP ?

Thinking about this a bit more, I think you've got a major problem with the Omada range. To use the public IP addresses on the LAN you need to be able to disable NAT . AFAIK that's not possible on any of the Omada range.

I'm confused, who is using a public IP address on a LAN connection?

Sorry for not being able to reply earlier, I was travelling most of yesterday.
As regards public IP's , the whole idea of a multiple IP block is that you can use some of the public IPs on devices in your LAN, for instance a web or email server that needs to be public facing. The main network IP is still used via NAT for other devices that don't require a public IP.
The settings you've been given seem (to me) to be those applicable for a client using one of the public IPs on your LAN.
You currently have the WAN interface on the 7206 set for static IP with the default gateway set to 173.195.163.129 , is that correct ?
I don't see how 173.195.163.129 can be correct for the default gateway for the WAN interface, it has to be the ISP gateway and thus can't possibly be in your allocated subnet.
Are you sure the WAN interface should be static IP ?, its more usual for it to be DHCP or PPPoE. These protocols allow for the IP address and default gateway to be automatically assigned by the ISP.

@MisterW I understand, although the way I have always done what you suggested is to connect a switch to the incoming line from the ISP, then port 1 on the switch would go to a typical router and be used with NAT for the normal LAN, port 2 on the switch would go to the Ethernet port on my web server, port 3 on the switch would go to the Ethernet port on my FTP server, etc. I have never attempted to route static IPs through a router. Different methods for different people I guess.

I am sure as I have used this ISP at two other locations, both of which also have static IP addresses, one on a Mikrotik router and one on a TPLink router. I also have the email from their network engineer giving me the static IP address information to put in the router. Lastly, with that given static IP information, my laptop works with their fiber perfectly when plugged directly from their media converter into the laptop's Ethernet port, so obviously the connection and information work.

Were those single IP or IP block connections ? and what was/is the default gateway for those ?

That's confusing me too

Just re-reading from the beginning...
Lights show no activity on WAN4 or the fiber converter Ethernet port. Weird.
Is there absolutely no activity or just a brief burst ?
Do you have WAN online detection enabled ? If so try disabling it
