We’re seeing a potential problem when deploying Dual Modem Pepwave devices with SIMs from the same service provider. The problem arises when the SIMs have numerically adjacent IPs.
Here’s the scenario:
- MODEM 1 has a SIM with IP 22.214.171.124
- MODEM 2 has a SIM with IP 126.96.36.199
- the Pepwave assigns each modem a /30 causing the networks to overlap. In this case of MODEM 1, Gateway address is assumed to be 188.8.131.52 which lives on MODEM 2.
Using the force /31 won’t help in this case.
What are the work arounds, if any? ALSO, are there any technical documents that address or warn users of this limitation?
