Native VPN client on android phone

[jdprovine]

I recently upgraded my PA 5050 to 7.1.9. Before that users could connect to the VPN could connect via their native VPN client on their android phones and today I got a call saying one user no longer could and it was failing on the encryption. Any ideas?

@jdprovine,

My initial reaction would be to verify that your x-auth setting didn't get reset to default and verify that they are using the proper group name and group password. It could be that the x-auth setting got modified back to it's default state or that their phone is simply misconfigured, since it specifically failed on encryption I would really be looking at verifying that the group name/password match what is actually on the firewall.

I checked and x-auth is enabled

If it had changed wouldn't it have affected pc native clients too

[jdprovine]

What about skip x-auth on ike rekey would that cause it to fail? and would it cause it to fail on pc native clients and phone clients

@jdprovine,

If you are utilizing the PC's native client then yes. At that point I'm guessing it's something on the users phone if you have native clients connecting elsewhere; I would ask them to clear everything out and follow your setup instructions again, they could have inavertably modified something without realizing it. Another question to ask with an native client is if there device has updated recently, the OEM could have changed something on there end that the PA doesn't like.

Thing is its a not a regular user but a networking guy LOL. So it probably doesn't have anything to do with the upgrade to the new OS of 7.1.9 on the PA

@jdprovine,

I would say with 98% certainty that this has nothing to do with the update to 7.1.9 if you are having clients utilizing native clients currently without any issue.

@BPry

Yes that was my thoughts as well since the release notes never mentioned any changed to the GP

Off topic: what OS do the computers have where you are using the native client?

@Remo @BPry

For now I only have reports of issues with the native clients on an Iphone and an android phones no word about pc's yet

@jdprovine

I'm really interessted in the OS, just because with windows 10 I was not able to configure it. And the reason after a little troubleshooting was that paloalto does not support strong enough ciphers for windows 10.

@Remo

so far I have tried it only on windows 8, I know you cannot configure the native client on windows 10 to work with the PA VPN, I am also going to test on a mac. I was also able to connect with the cisco vpn client and no longer can

[jdprovine]

would the tls version have anything to do with it

[Remo]

I don't think so because the native iOS / Android VPN clients do not connect with an SSL VPN tunnel. They use a plain ipsec vpn connection

[jdprovine]

so could it be a encryption issue something with isakmp
