Comcast gateway LAN/router LAN conflict?

@scottalanmiller Sorry, I should have been more clear there. The static IP on the luxul's WAN side is 50.193.X.X /30. The lan side on the Comcast is 10.1.10.0/24 and the lan on the Luxual is the same 10.1.10.0/24
Time to try my ASCII art so we can visualize this:
Comcast Luxual Local Net 10.1.10.0/24 --> 50.193.x.x/30 --> 10.1.10.0/24I'd say you need to change the local subnet or get a new subnet from Comcast, either way works. Probably easier to change the Local Net.

@travisdh1 it's way easier to change the LAN subset on the Comcast which a is a quick fix. The long term fix would be to change the LAN IP scheme behind the luxul. They have a lot of misc devices with static IPs on the LAN that would all have to get updated.
-
@JaredBusch They pay for a dedicated static IP from Comcast. What would you call it if not a static IP?

I generally avoid calling Tier 1 support from my ISP whenever possible, it always feels like walking into the dragon's lair.

Can you ping that 50.193.x.x address from outside your local network?
-
@travisdh1 yes. I can ping the Comcast's gateway IP and the usable IP configured on the router.

From outside your local network? You shouldn't be able to reach the 10.1.10.X subnet as it's a private IP range.
-
@travisdh1 The usable WAN ip address that's configured on the WAN side of the router.
-
Just to clarify, here in Oregon when you pay for a static IP address from Comcast (either a single or in a block of 5) you have the gateway's public IP address, then the usable public static IP address that you can assign to your router.
-
Just imagine this, but with the LAN subnet on the Comcast gateway to be idential to the LAN side of the linksys router.
-
Don't get hung up on the static address. I think he was assuming you had DHCP. You either need to change the subnet on the Comcast gateway or the Luxul router.

A fixed IP.
It is of course possible that Comcast is using a a true static IP assignment. But it is unlikely.
If it was a true static, then your comcast modem will have another public WAN IP and the /30 you have is routed behind that.
