Model: ER707-M2   ER605 (TL-R605)  
Hardware Version: V1
Firmware Version: 1.2.3

Hello everyone,

 

I currently have the following situation:

 

Site A: ER707-M2 + OC300

 

> The router dials in via PPPoE and receives a fixed IP from ISP. This is the main location in a server room.

 

Site B: ER605 + PoE switch + 3 APs

 

> This is another location that is to be managed via the OC300. Also dial-in via PPPoE, but a public, sometimes changing IP. Not a fixed one.

 

Now to the problem / question:

 

Site B is currently managed via port sharing on the Internet at Site A. This was the simplest option at the time of setup. https://www.tp-link.com/de/support/faq/3641/

 

However, we now have the feeling that, for example, the portal loads a little slowly, sometimes there may also be WLAN problems, roaming doesn't work properly, etc.

 

So the question arose as to whether port forwarding via Internet to the OC300 might have been the worst solution for us? Is a VPN, on the other hand, better or faster and more stable? The problem would be that location B has a changing public IP.

 

What do you think?

Hi,

 

I'm not sure why there's a problem with your current configuration.

The question is - why there's an issue with connection between side B and your controller. If that's ISP's issue - the VPN may not help here.

Have you tested a simple PING from side B to your OC? For some longer period of time to see if you are loosing packages somehow?

 

But regarding your question - you can establish Client 2 Site VPN - for example WireGuard. Your side B would be a client, therefore it's changing IP doesn't really matter. If the connection get interrupted somehow, in theory should be re-established back once the internet/server are available.

 

I do have such configuration now established between my main ER707 and site ER605, but - to be fair - I'm not utilizing it as heavily as you are.

Hi @TW_EPC 

Thanks for posting in our business forum.

There is basically no difference between the VPN and the port forwarding in latency.

Okay, if that makes no difference, then everything seems to be okay. Then there must be a problem somewhere else.

 

The connection is permanently stable. We are the ISP ourselves. Of course, we could also give both sites a fixed IP somehow, but we don't want to.

 

The portal authentication issue is the most noticeable. I have already reported this separately. It basically works very well, but is sometimes extremely slow.

 

Well. I'll keep looking...

When other people funnel into the same terminal, it could cause congestion. This is when the commercial line comes into play. That might reduce the latency depends on ISP optimization.

In fact, we have activated gigabit synchronisation at every location. So that shouldn't really be a problem.

 

Even the first device in the WLAN takes a few seconds to call up the portal. But it can also be normal, I just don't have the experience.

Hmm. I mean the dedicated line from your ISP for commercial and enterprise. It is not about the UL/DL.
