Mobile IKEv2 VPN Through Hotspot with newer Samsung Mobiles

Hi All,

Wondering if anyone has a similar experience.
We have some users tethering through newer Samsung mobiles (S24) for example and when they VPN from their laptop through these devices we get an established VPN but no local network access on the device.

I get some web traffic checking the WG logs and I can see connection requests to an internal piece of equipment but that's it.

It's almost like its unable to contact devices on the VPN entirely or traffic is being blocked on the Samsung device.

The same User can put their sim card into an iPhone or older Samsung phone with the same laptop and VPN through hotspot and connect to the internal equipment no problems at all.

It's like the devices are filtering non-standard ports perhaps ?

Anyone have any insight or ideas where we can go and look ?

Note we have already gone down making sure the APN on the Samsung device was limited to IPv4 and not trying to NAT through IPv6 or anything like that.

I know this doesn't make any sense given the VPN is on a different device and it's just hotspotting through the phone, it should either work or not.
But that doesn't seem to be the case.

    Hi @Pat
    I'd suggest opening a support case so we can help gather more data. If moving to a different phone on the same carrier with the same SIM card is correcting the issue, it's very likely something on the phone causing the issue. It may be something that the phone manufacturer and/or carrier need to fix, but we can at least help provide that data.
