I did notice the that interface we have named br-lan did not have the proper broadcast and netmask information. I adjusted that and it looks like its now connecting but still running into issues.

Here is a snipet from the new system we are trying to connect in (from the /var/log/tinc.log file)

 I changed the /etc/config/tinc file for testing just listed only two sites to connect to. Below is for the new 100 site im trying to connect into the network.

config tinc-net NETNAME
        option enabled 1
        option logfile /var/log/tinc.log
        option debug 5
        option AddressFamily ipv4

        list ConnectTo pfsense201
        list ConnectTo pfsense12

        option Name pfsense100

        option PrivateKeyFile /etc/tinc/NETNAME/rsa_key.priv



config tinc-host pfsense201
        option enabled 1
        option net NETNAME
        option Address PUBLICIPOFTHISSITEHERE
        option Subnet 172.16.201.0/24


config tinc-host pfsense12
        option enabled 1
        option net NETNAME
        list Address PUBLICIPOFTHISSITEHERE
        option Subnet 172.16.12.0/24

Summary, it looks like its connecting BUT when I ping I get time out and I cannot visit any http either. I looked at other users issues with connectivity and no ping but cannot determine the issue running wireshark. Any ideas?

Thank you again for the guidance!
Chris

I am having issues adding an additional site as it will not communicate with the rest. I have taken the firmware of one and flashed it on another router to make it duplicate and then tested it working but when I change the hostname, and IP to what we need it to be (in this case 172.16.100.0) it no longer communicates with the rest of the network even though I have the same public key (they all have the same key) as well as adding it to the host folder and tinc config file on every other router. Am I missing something? The current system seems to be working now but having issues to add new.

I suspect you do have an error in your configuration somewhere. Either on the new node, or in the other node(s) that will have connections with the new node. Check for typos.

I'm no pfsense expert. But why do some lines have ConnectTo=pfsense with a = sign between ConnectTo and pfsense, and other lines have a space instead of the =?

I see only two ConnectTo's here, ConnectTo = pfsense100 is missing.
Could that be the problem?
