That's a known issue with L2TP/IPsec on Windows Clients. See the warning here: https://doc.pfsense.org/index.php/L2TP/IPsec I've move on to IKEv2, L2TP/IPsec is not a good choice these days.

Guessing that's not your mobile P1 you're looking at. The others are only applicable and configurable for mobile.

You remove the input validation to get that to work? There are reasons that config isn't permitted by the GUI. It should come up fine when traffic triggers it though.

Split this to its own topic as it's not at all related to the thread you posted in. "received INVALID_ID_INFORMATION error notify" means your identifiers don't match. They wouldn't have before the upgrade either, racoon just (wrongly, really) didn't care. Info here: https://doc.pfsense.org/index.php/UpgradeGuide#Stricter_Phase_1_Identifier_Validation If you're using non-IP identifiers, you'll need to switch back to aggressive mode, and fix the P1s on both sides so the identifiers match.

By chance it is possible to use an OpenVPN tunnel between site A and Site B, and after create a Pfsense rule to send packet from site A to site C? thank you

Got it fixed. Ive put the local nets Ingo the routing section, seperated by space and everything works now AS it should. Not sure if all traffic is Router through the ipsec Tunnel, but that isnt important for me.

Just to follow up again this Error seems to hit the main dashboard page if the IPSEC Widget is enabled and also affects the Statis->IPSEC page.

Hi, i know that mikrotik + pfsense  is working. Is phase1 ok ? –>yes go to phase2 is phase2 ok ? From mikrotic forum: When you want to make a direct IPsec tunnel between MikroTik routers you must make sure that you have an exception rule in your NAT table for traffic from the local to the remote network which says "accept" (before your general rule that says "masquerade" or "src-nat"). When you do not do that, the router will mistakenly NAT the traffic before it puts it into the tunnel, and no communication will be possible. I used on phase 1 Encryption algorithm AES 256 Hash algorithm | SHA1 DH key group 2(1024) Lifetime 86400 phase2 Protocol ESP Encryption algorithms AES (auto) Hash algorithms SHA1 PFS key group 2(1024) Lifetime 1800 With other setting i ran in trouble. regards max |

Have just added IP range of my local network to VPN Connections > Static Routes tab in the AWS VPC console and am now able to access AWS Private subnet hosts from local hosts but not from the router itself.

jimp, thank you for the clarification. Regards yarick123

@burlugoz: Services > Proxy server > General You have to check field "Bypass proxy for Private Address Space (RFC 1918) destination". If unsuccessfull, input address  spaces of all your local networks (or just lan-IPs of yours routers) into field "Bypass proxy for these destination IPs" (for example, "192.168.1.0/24;192.168.1.0/24" or "192.168.0.0/16"). Also check your NAT settings. It will be a good idea to configure Outbound NAT traffic rules manually. This settings work good for me: "Interface=WAN; Source=192.168.0.0/16; Source port,Destination address and Destination port=any; NAT address=WAN Address; Static port=YES". Good luck;) thank you! :D one last question is it possible to setup squid and squidguard at the main  and have all traffic pass though the IPsec vpn? I want to setup squid and squidguard at the main office only and be able to filter though the vpn. does that make sense?

That did it!  Proxy ARP to the rescue. Added the subnet under Virtual IPs and BAM!  A tunnel I had previously established that was constantly pinging and printing failures all of a sudden started returning ping times.  :D Thank you very much for the quick reply and the hint!

@cmb: brevilo: your issue is different, please start your own thread. Fair enough. It looks similar to this and I'm gathering logs right now…

@brevilo: I'm still having connection issue after rekeying (incl. multiple SAs) with 2.2.5 at both ends. I understood that the workaround above shouldn't be required anymore. Is it sill? No it's not. There are no longer any general issues along those lines (though any number of config issues could potentially result in symptoms like that). Start a new thread describing what you're seeing, and what your logs show.

By "local network address", you mean the IP that actually gets assigned to the AWS instance? AWS doesn't allow that, it must be NATed.

@ocset: Hi I have successfully set up a VPN connection between my pfsense firewall and an Azure 2012 Server. I can see the server from within my network (ping, view shared folders etc) but I am unable to see my network from the Server. The network setup is as follows: Office network - 192.168.0.0/24 Azure network  - 10.0.0.0/24 (IP range 10.0.0.4 - 10.0.0.254) Azure Subnet 10.0.0.0/27 (IP range 10.0.0.4 - 10.0.0.30) Gateway 10.0.0.32/29 (IP range 10.0.0.36 - 10.0.0.38) The Azure server has a DHCP address of 10.0.0.4 and a gateway of 10.0.0.1. I don't understand why a gateway of 10.0.0.1. Based on my network config above, I would have expected the gateway to be 10.0.0.36 or higher. I can't ping 10.0.0.1 but can ping 10.0.0.36 from both networks. I have tried changing the Server's default gateway to 10.0.0.36 without any luck. I have disabled the firewall on the Server and created a firewall IPsec rule on the pfsense box to allow all TCP/UDP traffic from everywhere on all port. Still no luck Anyone know what may be wrong? Thanks O. Try setting your firewall rule to be for protocol "any" instead of TCP or UDP. That way pings can get through (they use ICMP). Also, does your LAN have a firewall rule allowing inbound traffic?

L2TP/IPsec is troublesome. You are better off deploying IKEv2, which works fine with the client built in to Windows 7.

@doktornotor: Basically, no… https://redmine.pfsense.org/issues/475 i hope this is no longer a limitation with pfsense 2.2 Refrence : https://doc.pfsense.org/index.php/L2TP/IPsec I will try implemnting it and see if it works.
