PFSense 2.0 - Not able to bridge tap VPN.
-
Show the output of "ifconfig -a"
Also if you switched between tun/tap on an existing connection, you must reboot. An unfortunate fact of dealing with tap interfaces.
New connections should be fine for that, you just need to make sure they're assigned and bridged to LAN on both sides.

Here is the output (note:the lan iface is dot1q trunked into the switch.)

That appears to be OK at a glance. Looks about like my VM test setup that works (though it doesn't use vlans)
-
that's exactly what it is, if this works then I get to buy me real hardware to use for pfSense. The vlan part of it works fine, I can ping on lan etc. But what to do about TAP?! driving me crazy.
How can I test firewall rules? -
Set the rules you have to log - if the packets hit the rule and log as being passed, then firewall rules are not your problem.
Doing captures on the tap interface on both ends while you try can help.
Is this a site-to-site or are you bridging in remote access clients?
-
Ok- I solved it. There is a problem with bridging the vlan interface. Either a bug or a incompatibility. I noticed a message on the console something to the effect of problem adding the vlan-iface to bridge0. (I had only been using ssh so hadn't seen the message) So I switched off a vlan interface to a real one and all was copacetic. Too many variables makes for a tough diagnosis.. Thanks for your help!
-
Tugi, I tried your suggestion, but now, OpenVPN do not want to start with "–server and --server-bridge cannot be used together". How did you overcome this?
-
Forget it, I installed the OpenVPN patch and it works great! Thank you.

Hi,
Thanks to Jimp for the ovpn bridge fixes in 2.1 which worked great in my testing. (Spent a lot of time trying to get 2.0 and 2.0.1 to work but never succeded).
Is there or will there be a way to specify the client IP address connecting to the OVPN bridge in the GUI? I currently use this for some clients whose IP address must remain static on the bridge. I am guessing I could put the ifconfig-pool-persist directive in the advanced configuration but was wondering where the file (with the respective client to IP address) the directive points to should be saved?

Probably would work with something to make the IP static in a client-specific override entry. Not sure what it would be offhand for a tap IP, but I thought it was supported (I know it is for tun, but the syntax is likely different)
