IPSEC-VPN failes to connect after ISP-IP-Renew (at night)

[itschloegl]

Hello all,

the following problem:

Since the update to 2.5.2, I have the problem with two VPNs that the corresponding IPSEC-P1 tunnels no longer connect after the forced disconnection by the ISP at midnight.

The IPSEC-LOG then only says

05[NET] error writing to socket: Can't assign requested address

If i stop and start the IPSEC-Service over the webinterface, the Tunnel connects normally again until the next forced separation.

Notes:

PfSense (Hosted; 2.5.2) with fixed ip

--> IPSEC (v2) Connection to site 1 (pfsense 2.5.2)
--> IPSEC (v2) Connection to site 2 (pfsense 2.5.2)

Problem with both sites (over night)
