GUI option to set RADIUS Timeout for EAP-RADIUS
There is currently no way to adjust the RADIUS timeout for EAP-RADIUS authentication in conjunction with Mobile IKEv2. The "Authentication Timeout" setting in System -> User Manager -> Authentication Servers is ignored.
Instead the following defaults are used:
charon.plugins.eap-radius.retransmit_base = 1.4 Base to use for calculating exponential back off. charon.plugins.eap-radius.retransmit_timeout = 2.0 Timeout in seconds before sending first retransmit. charon.plugins.eap-radius.retransmit_tries = 4 Number of times to retransmit a packet before giving up. charon.plugins.eap-radius.sockets = 1 Number of sockets (ports) to use, increase for high load.
To use 2FA/MFA with RADIUS the timeout needs to be adjusted to 60s, retries eliminated, and sockets need to be adjusted to allow more than one concurrent authentication.
it would be nice to add "RADIUS Advanced options" to vpn_ipsec_mobile.php
