Ipsec not passing traffic randomly



  • I am having issues with mobile clients not being able to connect. Most of the time they can connect normally but every now and again they connect but cannot pass traffic at all. This is for people who are using shrew and the built in mac client. I have been told that when they cannot connect on their laptop they can connect using their IPad and it brings the laptops tunnel back to life.

    Any suggestions as to what the problem could be?
    Any other information that would be useful to have to help try and fix this?

    I have followed the guide https://doc.pfsense.org/index.php/Mobile_IPsec_on_2.0 so its exactly the same with the exception of "Encryption Algorithm: AES 128" being 3des as this was what was setup for the Cisco firewall we were using so it saved us having to push out a new config.

    I am not sure if this is related to this bug https://redmine.pfsense.org/issues/1351
