Hi all, I had an encrypted serial-to-TCP-to-serial stream on a Raspberry Pi and am basically trying to replicate it with the Teltonika RUT955, which I've never used before. I think I have all the IPSec configurations correct in the Teltonika menu and here they are for reference (I feel confident the security settings, encryption, etc. are correct so not including them here):
Router #1
left=10.10.x.10
leftsubnet=10.x.29.0/24
right=x.x.x.x
rightsubnet=x.x.30.0/24
Router #2
left=10.10.x.11
leftsubnet=10.x.30.0/24
right=x.x.x.x
rightsubnet=x.x.29.0/24
Sorry if those IPs don't make sense, I am still very new at this. But the ones visible are the only ones that matter. They are going to a 3rd party server so the right is the same for both.
Now I start with the IPSec down but the PPPoE connected and need to create routes since otherwise the data will just go straight through the ethernet and not actually use the IPSec tunnel (when I WireShark I just see TCP packets not ESPs).
So I do the following commands in CLI for Router 1:
ip route delete default
ip route add x.x.x.x/32 dev pppoe-wan
ifconfig eth0:1 10.x.29.1/24 up
ip route add default via 10.x.29.1 dev eth0:1
ipsec up [name of ipsec]
You can probably infer what happens on Router 2, very similar just switching some IPs. After this the IPsec tunnel still isn't being used.
I know this is jumbled but it worked on my Raspberry Pi and I am struggling with the transition. I don't really understand the routes, just am copying what worked on the other machine, so there is definitely something I am missing here. The PPPoE also seems to be using a different program (?) so that is throwing me off too. Any leads are greatly appreciated, I am happy to post the outputs of anything that would be helpful. Thanks in advance for reading this mess.
