Greeting Peplink Team,
Refreshing on old Forum post from August 2015 (Subnet Selection Mode on Cellular WAN).
Would it be possible to create a feature which would allow for a forced /24 subnet and GW assignment of a .1 when router is placed into IPPT?
Competitive ref: https://docs.cradlepoint.com/r/NCOS-How-to-Configure-IP-Passthrough-on-a-capable-Cradlepoint-router/Subnet-Selection-Mode
Force /31 and custom would be, “nice to haves” as well…
Thank you in advance!
Hi…
I don’t know the Peplink plans for Cellular WAN.
But for eth WAN / eth LAN the use of /31 is working.
@bbarker ,
Are you discussing this use case ?
If yes, I suppose you need to change the WAN subnet for the LTE Router X using /30 or /31.
This is what have been explained by the ref that you shared. The ref explaining the issue when both remote site is assigned IP addresses are in the same network at multiple locations this will cause issue for the Internal router to connect.
For Peplink Router Cellular WAN, we have automated this to avoid the issue and this is the reason why you are getting /31 network without IPPT. When IPPT enabled, we will let the module to calculate the subnet based on the IP obtained and it will normally in /30 network because some of the device cannot support /31 network.
Please let me know if you need more explanation.
I second this request. I work with a lot of customers and multiple vendors. We currently have a customer starting a big migration from Cradlepoint to Peplink and this feature has the customer questioning if it’s worth it due to having to reprogram all his actively deployed Firewalls. The CP’s are setup with the "force /24 subnet option now.
