GRE packets dropped when accessing a VPN
-
Hi there,
I'm sorry about misunderstanding your point about the modem. I don't know why I setup my mind on a dialing modem.
How can I check up either my modem is in rounting or bridge mode? This is the first time I'm dealing with this issue.

when i sayed dialing?
*dsl / cable - modems do exists alsoTry to search from google with your modems/routers name and model and add username/password
-OR-
you can try this -
I can sign in and check the settings of my modem. Is that what you mean?

Is your setup bridging or routing?
-
It's a routing setup!!!!
-
And you're having double nat with pfsense?
so that pfsense has something like this:
wan: 192.168.100.10 /24
lan: 192.168.1.1 /24? -
Yes, I have
Lan: 192.168.1.2 / 24
Wan on DHCP: range 192.168.15.x / 24
As extra information, I'm doing NAt on port 80 and forwarding to one IP in the subnet.

Well,
GRE is part of ip, but not tcp or udp, it's not a port which you can forward to, unless you're having separate support to it.
If it is possible by anymeans, change to bridging configuration and then GRE should work a bit better -
Got ya!!!,
I wouldn't like to switch to brigde mode since I can lose some of the advantages over routing. Meanwhile I'm accessing the VPN from a pc out of the firewall.
Now, what is the GRE tunneling on Interfaces used for?
Thanks in advanced again for all your time and help.

May i ask what is so big advantage to route in a modem vs firewall?
-
I focused on the advantage of routing over bridging in a firewall. I can not tell on the modem. I've bin trying to find where I can switch my modem to the bridge mode without luck. I'll check GRE on wiki. Any suggestion from you is valuable.

I only tried to suggest that, change your modem to bridging and use only firewall in routing mode.
that ease a bit to troubleshoot gre and other things also.
