Thank your ! After I added 192.168.101.0/24 to remote networks in branch office,  all working fine! 102 addres - it was my error while i write this message.

For a working solution, have a look at reply #3 from phil.davis on this thread: http://forum.pfsense.org/index.php/topic,70066.0.html

Interfaces > (assign), assign the VPN and then enable it with an IP type of "none", then go back and edit/save the VPN to make sure it's started back up OK. After that you should see a gateway for the VPN in System > Routing, and you can use that gateway in firewall rules to make traffic exit that path. Depending on the other side you might also need to setup manual outbound NAT rules to do NAT as the traffic leaves the VPN

The most likely cause in this scenario is that your per-interface rules are not being matched as you expect. If the VPNs are assigned with an IP type of "none" as they should be, make sure you are not using the macros for things like "VPN_1 subnet" and similar. With an IP type of "none" those are really blank/null. If you specify the actual subnets there, the traffic can be matched.

Well… (feeling kinda stupid) :P I got as far as step 2 and it started working like expected. I haven't had to reboot PFSense devices in ages and didn't occur to me. In my defense, they were also in production use so was not convenient at the time. Problem solved IPSec had something left over after disabling tunnels that a reboot resolved. Thanks Marvosa...

@marvosa: Need to clarify some info: Your diagram shows "OpenVPN Tunnel Network: 10.0.10.0/24" and "Subnet to pfSense3: 10.0.10.8/30".  Please clarify what you meant because those networks overlap. When you say "I have a remote site connected with OpenVPN Peer to Peer (SSL/TLS) working" you never specified what was connected. I can only assume from your diagram that you meant PFsense 1 and PFsense 3 are connected and that each side can communicate with the other side's LAN, but please verify my assumption is correct. On PFsense 2, is there a typo or is 172.16.10.1/26 really a WAN interface? Why isn't it a LAN interface?  I would imagine 172.16.20.0/26 cannot communicate with 172.16.10.0/26 because there is no return route back to 172.16.20.0/26 on PFsense 2.  Although, I'm not even sure that's possible because it's a WAN interface and being NAT'd… someone else chime in if they know for sure you need a return route to 172.16.20.0/26 on the cisco.

This mysteriously started working.  The only thing I can think of is that I a reboot of my Ubuntu Laptop or pfSense server fixed the issue.

Fair enough.  Like I said, though, I am literally the only person who has access to this VPN.  Thanks, I think I will figure out how to secure access from the VPN subnet just to be safe, and remove the NAT rule…

It worked! Thank you for your patience! I didn't even think to change the "LAN" part of that config. I was kind of assuming that once you're VPN'd in, you're part of the LAN.

ah yes… I have later forgot/overseen the 1st change which calls the update routine... --- /usr/local/www/system_crlmanager.php.orig 2013-04-12 16:31:46.000000000 +0200 +++ /usr/local/www/system_crlmanager.php 2013-11-29 23:21:22.000000000 +0100 @@ -107,6 +107,7 @@ } if ($act == "exp") { + crl_update($thiscrl); $exp_name = urlencode("{$thiscrl['descr']}.crl"); $exp_data = base64_decode($thiscrl['text']); $exp_size = strlen($exp_data); @@ -580,11 +581,9 @@ - [" alt="" width="17" height="17" border="0" />](system_crlmanager.php?act=exp&id=<?=$tmpcrl['refid'];?>) - [" alt="" width="17" height="17" border="0" />](system_crlmanager.php?act=edit&id=<?=$tmpcrl['refid'];?>)

Unless you instruct OpenVPN to push a default gateway, only the network you specify when you setup the tunnel will be accessible through the VPN. Since I'm with XS4all I have WebTV and native IPv6. So I'm pushing routes to the webtv network in addition to the local network. All other traffic remains outside the tunnel. Since you want to send all traffic through the tunnel you have to push a IPv4 default gsteway. You can do this in the tunnel setup. To have IPv6 everywhere I push a IPv6 default gateway always. But as you do not have IPv6, don't worry about it. The only thing you have to do on the PFS box is to make sure that all traffic is forwarded through the other OpenVPN tunnel. In my ignorence I assumed it was an IPsec tunnel. As said, with an Atom processor without HW encryption I get 60Mbps.

Completely reinstalled pfSense and what do you know?  It's working. Hypotheses: Corruption of original installation and/or Using older version of OpenVPN Client Export pacakge and/or Some other installed package caused a problem (have installed this fairly lean on this occasion). Thanks to all for your help.  I'm going to snapshot this virtual machine while it's working!!!
