Set up GRE tunnel. Sendto error:5
-
Hello.
I attempt to set up a GRE tunnel,but it has something not right.
While i'm pinging one pfsense to another,it doesn't work.
I went to configuration to view the "system logs" . It said "Sendto error:5".
My firewall has configured.Pfsense version is "CE-2.6.0-RELEASE."
Issue :-
What does the error code means?
-
Is there any configuration that I need to modify?

@vuiora said in Set up GRE tunnel. Sendto error:5:
Sendto error:5
It's an Input/Ouput error: https://man.freebsd.org/cgi/man.cgi?query=errno#RETURN_VALUES
So maybe there's no link on the NIC it's trying to use?
More info needed.
