      Are any of the other remote devices a pfsense version lower than 2.1?

        There are 2 pfSense 2.0.3 boxes & 1 Cisco 1841 router.

        NB: I even tried rebooting both pfSense boxes but that did not make any difference.

          I have experienced a similar problem.  I have 2 pfSense 2.1 boxes in different locations with static ips.  I set up a simple IPsec and got it working.  After 24 hours, the traffic flow dies, but the VPN shows it is UP.  Can't ping or anything.  Reboot both pfSence's and the VPN might work, or might not connect at all.

          IPsec in 1.2.3 was rock solid!  In 2.1 it seems VERY flaky!  What happened???

            I am no expert, but under System/Advanced/Firewall NAT is "Disable Auto-added VPN rules" checked?

              Thank you for your replies.

              @Swissnic: I remember that when I first set up the VPN, it was working fine. The next day, it wasn't! Rebooting has not solved the problem.
              @newbieuser1234: On both pfSense boxes, the "Disable all auto-added VPN rules" option is NOT checked.

              If there are other people with the same problem, maybe it is a bug?
              But strangely, it is working absolutely fine for the other 3 IPsec VPNs!

                dumb question, but can you access the webconfigurator on the remote lan?  Are you running snort or anything that could be blocking them.  I added some aliases and whitelisted my ipsec tunnel addresses in snort.  just a thought.

                  At this point, no question is dumb.
                  No, I cannot access the webconfigurator via its remote local IP address.
                  But, I do have access to it via a public NATted IP address, i.e., I can make any change if required.

                  Snort is not installed on either pfSense.
                  Only ntop is installed on the remote one.
                  On the local one, HAVP (not enabled/running), iftop & mailreport are installed.

                  Thank you for trying to help.

                    What do the ipsec logs say?

                          The file /tmp/rules.debug contains some references to snort, but this package is not listed in the list of installed packages!
                          Is this normal?

                            I am not sure.  Can you just roll back the 2.1 install to 2.0.3 if your others are working fine? I have seen some other threads with ipsec issues and 2.1.

                              I will try to do that as a final resort.

                              Today, I deleted the SADs & SPDs for this tunnel via the Status->IPsec menu on both pfSense boxes.
                              Then, I manually initiated the tunnel connection from the local pfSense. This time, the tunnel is NOT being established successfully!

                              Below are extracts of the IPsec logs on both pfSense boxes:

                              There seems to be a problem during phase 2 negotiation, but after checking the 2 configs, I don't find any problem with both phase 2 parameters.

                                I edited both phase 2 configs & set the the lifetimes to be 3600 (they were 86400) and saved the configs.
                                Then, I refreshed the IPsec status pages and the tunnel showed as "active".

                                But of course, I still cannot ping/access the other network!

                                I restored the lifetimes back to 86400 and the tunnel is still showing as "active", but the remote network is still not accessible from the local network, and vice-versa.

                                Strange?

                                  2 days ago, I restarted the local pfSense box (version 2.1), then pinged a couple of hosts on the remote LAN and the pings were successful!
                                  Now, it's not working again  :( /  >:(

                                  It seems there must be a problem with IPsec on 2.1.
                                  As soon as I get some time, I'll install version 2.0.3 and see whether the problem persists.

                                  Thank you.

                                    I upgraded to the 2.1.1 PRE-RELEASE version without any success.

                                        Why are hesitant to roll back to 2.0.3?

                                          Yes, you are right.
                                          I am trying everything possible before the last resort of rolling back to 2.0.3.
                                          I think I got used to the interface, the traffic shaping queue status, …

                                          I'm even trying OpenVPN, but having the same problem, which is making me wonder whether the problem is elsewhere!
                                          The OpenVPN tunnel is UP, but I'm unable to access either remote LAN hosts.

                                          Will update this post if I do find the cause of this problem.

                                            We have the same problem, tunnel is up but no traffic in both directions.When I restart racoon on both sides I have traffic but after some time this stops while tunnel status still shows up.

                                            We use the special hyper-v 2.1 build.
