Can I route internet traffic from site B through site A via Ipsec VTI?
-
Here's the rule it says is cashing the event. Default deny though I'm confused how that is if I set an any to any rule.
-
Noticed that the screenshot I took had a lot of private to private network events. Here's one more that shows internet to device events. Same rule.

Very strange.
104 the rule blocks all outgoing traffic, but it should not work
Try to do that is a floating rule for the IPSEC or VTI interface
-
Done. See the below screenshots just to make sure I didn't do something wrong. No advance setting changes were made.
-
Still seeing the same issue flagging on the same rule.

And if you check QUICK ?

Same deal - logs are on fire. I really wonder if I'm trying something that isn't fully implemented in pfsense/freebsd. I've done a ton of web searches and haven't been able to find anything that matches. Part of me wonders if site A forgets or cannot remember/track the connection and so when something comes back from the internet the router at site A it says "what's this request for 192.168.2.2?" and then blocks it or parts of it.

The first time such see
Show me what the command shows
pfctl -sr | grep enc0
(WebGUI /Diagnostics/Command Prompt/) -
pass out on enc0 all flags S/SA keep state label "IPsec internal host to host"
pass quick on enc0 inet all flags S/SA keep state label "USER_RULE"
pass in quick on enc0 inet all flags S/SA keep state label "USER_RULE" -
@ngoehring123
And still try in floating rule put option TCP Flags - ANY Flags and State type None
-
So firewall is still having events however now the interface has changed from ipsec to IPSEC_VTI. ???
-
@ngoehring123 said in Can I route internet traffic from site B through site A via Ipsec VTI?:
IPSEC_VTI
That's the same floating rule , but for IPSEC_VTI ?
There will be two identical rules , one for IPSEC and the other for VTI -
I just have the one floating rule for ipsec. When I made those last changes you suggested the firewall errors started saying IPSEC_VTI instead of ipsec. I had to disable those last changes as they resulted in me losing access to the remote router. Thank goodness for openvpn.

@ngoehring123
Excuse. I didn't think there would be such a result. I have no more ideas )))
-
No worries my friend. Your time and effort is greatly appreciated. Here's to hoping this gets sorted out soon. I'll be sure to share the fix with you. Thanks again!

I would consider an option of the usual IPSEC tunnel, through it too it is possible to pass a traffic outside.

I had thought of doing that as well but really like the routed option more due to its flexibility and power. Perhaps @jimp has some tips for me.
-
The really weird thing now is that my phone says I have no internet connection yet here I am writing to you and browsing the internet. Something is ascew...
-
@ngoehring123
That's possible. I myself use the GRE over IPSEC option and do not want to switch to VTI yet.
Will wait to hear other forum members -
@ngoehring123
In this forum, I read that some remove the VTI interface, re-create the tunnel , and the problems are solved
