just add a static IP associated to the line.
I'm little bit confused.
Looking on the contract I see :
- Static IP range : xxx.xxx.xxx.169 - xxx.xxx.xxx.169
- Subnet : 255.255.255.252
- Gateway : xxx.xxx.xxx.170
However if I check what is my public IP, I see : xxx.xxx.xxx.170
Shouldn't be xxx.xxx.xxx.169 ?
Hi TheFwGuy and welcome to the business forums.
I appreciate you reaching out in regard to statics. I'll be glad to assist.
The gateway address refers to the address loaded onto your gateway. All statics no matter the amount, come in a block. Using the example above, xxx.xxx.xxx.170 is what is loaded into the leased Comcast gateway. This would not be used for any personal devices as this is what is used to communicate with your static IP range.
The static IP range refers to your usable IP addresses. This is what is used for your personal devices. Example being a server or firewall. I hope this clears up any static inquires. Please let me know if you have more questions or need anything as the Digital Care Team is always glad to help here on the business forums!
Well, uhm ok. Here the situation.
The Comcast modem is connected to my router.
Initially I had the dynamic IP and the connection between the Comcast modem and the router was via DHCP.
When I had assigned the static IP I didn't change anything so automatically them modem did set up the connection and I ended up with an IP I did assumed was the static one.
Now I did force on my router the expected data for the fixed IP and after rebooting it, the Comcast modem did assign to it the expected public static IP (xxx.xxx.xxx.169).
If I set my router for the DHCP toward the Comcast modem, this one assigns the xxx.xxx.xxx.170 address instead the expected one (xxx.xxx.xxx.169)
So it seems now I'm going out correctly from my main router.
However I like to complicate my life 🙂
I have also a backup unit (Cradlepoint) and I'm attempting to connect another router to it.
I did set up the other router expecting the same IP, however if I connect the router to the CradlePoint unit, is not showing up on the Comcast modem devices list and of course, no connection.
If I connect the second router to a port of the Comcast router directly is working, via the Cradlepoint unit not.
And anyway doing so the Comcast modem doesn't know where to send packets (two routers with the same IP) and nothing in the end works.
Any idea how to connect a second router ?
Even without static IP. The second router is only for backup in case the main line is down, just to have some connectivity
Thank you so much for supplying all of the information. From what you are subscribing you would benefit from an upgrade to your IP block. You only have 1 useable IP address and it is already assigned to 1 device. If you would like me to look further into upgrade options please reach out through private message with the name, address and phone number on the account.
