[pfSense] GRE tunnels don't have an interface

[Patrick Bihan-Faou]

Hello,

I am trying to setup a GRE/IPSEC tunnel using pfsense on one end and a
CISCO router on the other end.

This is a site to site VPN and I need to route some specific trafic via
the GRE tunnel.

I tried to configure the route manually, but in order to do so, I need
to have a gateway. So far so good... So I wen to the gateway page to
setup the peer IP address of the GRE tunnel as a gateway, but the
interface does not indicate the GRE tunnel in the interface list.

As a side note, I have the same issue for firewall rules. However there
I can create "floating" rules that will work properly.

This is somewhat odd, because freebsd represents the GRE tunnel as a
real interface (in my case gre0).


How can make pfsense see the GRE interface as a real interface just like
it should ?

Best regards,

Patrick.

Interfaces > (assign), make a new OPT interface, select gre0.

Then go to Interfaces > OPTx and enable and set whatever you need.

Hello,

Thanks a lot, I did find the trick after sending the message (as usual
with noobs).

I guess this is just obvious for pfsens-veterans...
