IPSec Tunnel Disables Interface??



  • I've noticed that when I have a IPSec tunnel up, the subnet it's pointed to no longer works on pfsense.

    Meaning that if 10.27.0.1 is the IP address on the interface the IPSec tunnel is terminated too.

    I can no longer ping that IP address from the LAN side, or if i'm SSHed into pfSense i can not ping or telnet out that interface.

    If i disable the IPSEC tunnel everything works as normal..

    For example, i could telnet to 10.27.0.2 from pfSense without IPSec enabled.

    With the IPSec tunnel up, i can not ping 10.27.0.2, or telnet to it.  I've noticed this on every single pfSense i have



  • check you ipsec rules, icmp may not be allowed to pass.

    No, i'm fine passing traffic over the tunnel,

    Its when the IPSec tunnel is enabled, i can't pass any traffic from pfSense to any of the IPs assigned to the LAN interface..

    For example, any device on the LAN can't ping the pfsense IP of "10.27.0.1" when the ipsec tunnel is up.\

    IPSec Tunnel -> pfSense -> LAN Device

    So between pfSense and the LAN Device is broken.
