Please help me with Router Configuration

Now that I can access synology from PC.1 (via inputing it’s ip), I notice that I cannot access it with SMB (SMB was the way that I used to work). Minor loss now that I cannot, but was nice to have it. (i.e. I could see the synology via my network in win10.

This could be firewall issue from Synology. Check it from there.

@sondo214

The next goal is to make the two Gl.inet routers (Opal and Slate AX) connect via “site to site”

You need to open new post later we cannot have all issues in one post.

Will do, thanks

I will try to tinker around and if I cannot make it work, I will open a new topic. Thanks

Your exact same setup:

Device as router with disabled NAT, additional routing rules

You mean as the problem we fixed in this topic?

Both router’s have a public IP

Neither Opal nor the Slate AX have a public IP. 4G likely have CG-NAT (=Carrier Grade NAT, so a NAT at the ISP so they can make multiple connections use the same IP). The Opal is behind the ISP router, so does not directly have a public IP.

As the instructions state, you can forward port 51830 on the ISP router to the Opal. That way the Slate AX can connect to the Opal using the public IP (of the ISP router) + that port.

Yes, indeed …

I have no good luck with that this far…

-I have enabled port 51830 in Opal

-I have enabled port forwarding in my ISP router

• But something does not work right…

If I cannot figure it out, I will start a new topic in the forum

Did you try setting it up again and make it run that test you showed earlier. Ports may look closed if nothing is running that is listening on that port.

-Both router’s have a public IP: I believe they both have. Opal through ISP router and Slate AX through a Huawei 4G mobile router (E5788).

No, incorrect!

[Opal through ISP router] it does have public IP because your ISP router is using DSL connection.

[AX through a Huawei 4G mobile router (E5788)] it dose NOT have public IP because your E5788 is using 4G connection - you are behind NAT even if you see online your public IP when checking online! In other words, it is a shared IP assigned for many customers by your 4G ISP.

@sondo214

-Port 51830: I guess I have to open this port to both ISP and E5788 router?

Incorrect!

You can only open this port on your DSL ISP router (since it has an actual public IP not NAT ). Then initiate the site-to-site connection from the AX router to be able to establish a tunnel.

Once you enable port forwarding on your ISP and setup a listening service on the Opal, then perform a test. if you enable port forwarding correctly but NO listening service on that port, the test will show a closed port!

Didn’t know that…

Didn’t know that either…

Will do that and report back! Thanks
