Help on changing a setup
-
Hey guys. So i am wondering if what i need to do is simple enough. Currently have a fiber connection in the office where my servers are. I am going to have to cut this and will be using a link that is a little distance from the office (4km), which i will PTP (Carrier class PTP's, 300mbps throughput) to there with some Wireless equipment. So i guess i need to know if i am going to have problems seeing that the WAN is not going to be located right there next to my pfSense box.. or am i best to move the server to the location of the link and just PTP the connection to where the main tower is (main tower currently on the roof of the office where the fiber link and servers are?

Anyone have any ideas/help that they can provide?

We are using a PTP link to 2 Providers located at 120Km from our servers, and all works fine.
All depends of what "some Wireless equipment" can do and what HW you have at the remote end…

thanks for that reply. Basically my ISP link will be located 4km from my main tower where my servers are.. so basically i am using some Ubiquiti PowerBridge M5 PTP to connect from the location that my link is, to my tower where the servers are located, to the PTP on the main tower will be connected to my WAN port on my pfsense server. I was just worried that i will have problems seeing that my link is connected from so far away, and not right there next to the server

Just config your PowerBridges as WDS (AP WDS <–> Station WDS) this way your link will be transparent at layer 2, same as have a 4Km UTP cable ;)

Yes, that is how they are already configured. SO this will not cause too much latency or slowness for clients seeing that the actual link is coming from 4km away?
I mean, the throughput will be higher than the speed of the link anyways..

At 4 Km, with a signal level between -60dBm / -65dBm and a Noise floor arround -90dbm your link must work OK
Using MCS15, with a 20Mhz Channel width, you get 130mbps, so for your 20mbps pipe it must perform OK.
I have done some tests using MCS10 at 20Mhz channel width (39mbps), with Nanobridge, and it can pass 20mps without problem.
