IPsec mobile fails with VPNC and "Network List" after 2.2.x upgrade
0%
Description
We usually use a wrapper client (Shimo) for vpnc that helps us with some route automation, but for purposes of simplification in troubleshooting this, I have recreated the exact error with a bare vpnc install. Same error seen on any version of VPNC I have managed to try. Always recreated.
Error on Client side:

there is something wrong here, though it's not clear what. The issue is replicable with Jody's config, and a slightly different config that works with iOS and OS X. Not sure if that's an issue in vpnc or strongswan, will investigate further later. Doesn't appear to be a config problem or a problem in anything we're doing.

I'm also having this issue. Please let me know if there is any specific information I can provide to assist. Everything was working on 2.2.2 and stopped working with the 2.2.3 upgrade.

Your issue is likely #4791 and not related to this ticket.

Thanks Jim,
That was my first thought, but it remains broken after disabling AESNI and rebooting (unless I did this incorrectly). It's still entirely possible that it's not related to this issue though.

Hi,
I can confirm that this issue is still affecting me - with the disable AES-NI workaround enabled. My iOS clients cannot connect anymore - all failing with "Wrong Shared Secret".

Hi,
Attached are the screenshots of the VPN configuration for this, along with a log file of the connection attempt. I hope it helps.

this ticket is specific to vpnc and only vpnc. iOS PSK issues in 2.2.3 is #4806
Updated by Carter Baller about 9 years ago
Looks like it has something to do with the "Network List" option in VPN: IPsec: Mobile section. If that is checked, I receive "ISAKMP_N_PAYLOAD_MALFORMED(16)" when attempting to use vpnc. ShrewSoft works fine.
I'm running 2.2.4.

2.3)
this looks to be a problem in vpnc. It works fine if you leave the "Provide a list of accessible networks to clients" box unchecked. vpnc can be configured to work around it. It isn't used much so isn't worth digging into further at this time.

This is/was affecting a large number of my geographically dispersed Mac OS X users using the "Cisco IPSec" configuration. This regression has kept us at 2.2.2, which isn't ideal in the long run. If there's a viable workaround for these clients I'm not sure what it is. Could you please provide information?
Thanks,
Ed

Sorry I overlooked comment #7. I retract my previous comment on this bug ;)
