SFC Relay LAN to LAN (BRIDGE)

General

Hi,

I am creating a LAN to LAN bridge for a full duplex telemetry device. I’m using a BR1 (Client) and BR2 (Host) Max with Speed Fusion Connect licenses.

I’ve spent about 2 days trying to achieve this. I first tried PepVPN, I had no static public IP address so I firstly wrote a DDNS server on AWS and even though the DDNS server was successfully updating the Cloudflare registary the BR1 could never make a successful connection.

Anyways moved to Speed Fusion connect using a SFC relay on the BR2 and having the BR1 connect as a client to the Aus Syd server. Set up an outbound policy and I was able to ping anything on the BR2 network from the BR1 but not visa versa. The BR2 could not ping the BR1 and I couldn’t set an outbound policy targeting the SFC tunnel anywhere.

I then set up a BR1 Relay server, I had to do it in a different geographical location (Singapore) which seemed weird (wouldn’t let me do Syd), and I have the BR2 connecting to the BR1 relay and set an outbound policy and it works! The BR2 can ping BR1 devices.

Now, I have a full duplex link, one half going through Singapore and the other half going through Sydney. This seems a little absurd. Is there any simple solution? Am I being a doofus?

So br1 and br2 same time client and server for each other?

I tested few days ago SFC RELAY client - server and only on 1 side outbound policy rules was available for SFC client connection. And LAN ping was to 1 side only.

@gabjol ,

This is the only option now to allow both devices LAN clients to communicated.

BR1 LAN clients ----> BR2 (Relay Server) LAN clients via the Sydney SFC location
BR2 LAN clients ----> BR1 (Relay Server) LAN clients via the Singapore SFC location

P/S: As for the current SFC Connect feature set, different SFC location nodes required.

Thank you for your feedback and we will definitely bring this to the Engineering team for the future SFC connect feature improvement.

As far as I’m aware. I was hoping somebody had a better method!

Had the exact same problem. LAN ping was half-duplex the client could ping the relay devices.
I can’t figure out a full duplex solution other than each peplink hosting a relay in a different continent. The latency is interesting.

I was pretty sure after this advertise:

“Internet access
like you never left

The SF Relay allows you to access the Internet through your router even if you’re physically away from it.”

that after connecting to peplink end point device in SFC Relay i will be able to configure OSPF or Layer 2 bridge as in the case of connection via peplink VPN. And I will have 2 side LAN connection.

Was think SFP Relay gives the same possibility as peplinkVPN, but due to paid traffic it will help to avoid the need for a static IP address on 1 side.

I completely agree and swear that’s what’s advertised as well!

I think it may be possible with IC2, but ultimately you’re correct. Peplink is not delivering the product they advertise, and the documentation on their enterprise products is ultimately bellow poor.

Really would be great to know if there is an alternative solution!
As the link is terrible, so much loss.

peplink good devices, commercialised more that i want.
I still happy to use them.

But exactly SFC relay should be improved as this is payed function, at least to have duplex LAN connection with more easy setup like speedvpn.
