Issue #3251
Can't connect StrongSwan by EAP-Radius
Affected version:
5.7.2
Resolution:
No change required
Description
I've checked extensively on strongswan issue & this question is already asked but I failed to use any of the solutions to resolve my issue.
I would like to create strongswan vpn for client, client just using account and password for authenticate in freeradius to connect my VPN.
when i connect from Ios it say User Authentication failed
here are my config files
