Description

see https://forum.netgate.com/topic/108637/ipsec-ikev2-with-eap-radius-vpn-azure-multi-factor-authentication
and https://forum.netgate.com/topic/128539/allow-setting-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:
https://github.com/strongswan/strongswan/blob/5.9.0/conf/plugins/eap-radius.opt:

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

works as expected on 21.05.r.20210526.1807 -
I can see advanced parameter in the `/var/etc/ipsec/strongswan.conf`:

        eap-radius {
            load = 2
            class_group = yes
            eap_start = no
            retransmit_base = 2
            retransmit_timeout = 5
            retransmit_tries = 6
            sockets = 2
            servers {
                localradius {
                    address = 127.0.0.1
                    secret = "123" 
                    auth_port = 1812
                    acct_port = 1813
                }
            }
        }

but it doesn't allow to enter numeric with a decimal point in the "Retransmit Base" and "Retransmit Timeout" fields.
fix:

but this is not critical

Open a fresh issue for that input validation concern, we can work on that for the next release separate from this.
