Layer 2 connection issue with Android to PC app
-
Hello,
So I don't know if I'm posting this in the right place or not, but it does deal with a Layer 2 issue I'm having. I went to support on this, but it is beyond the scope TAC Lite support and I was advised to ask here. I'm a beginner at this stuff, so anyway here goes. I am using a SG-1100 by the way.
My issue has to do with an Android app called Sweech and what this does is when you turn it on, it gives you an IP address to put into a browser address bar. For example, 192.168.0.x:4444 (where x ranges from 3-7). Upon doing that, it connects you to a WebUI where you can easily move files between the phone and PC wirelessly. However, the connection times out when the 1100 is in the mix. When it's not, the app works as intended.
I was advised by support staff that this app works by allowing connections between devices on the same Layer 2 broadcast domain and as such, this is unlikely to be a firewall issue and that it is likely something incidental to the firewall being in place. I don't yet know enough about how all this works and so I don't even know where to begin to look for how to resolve this.
My know-how with networking is fairly weak, so I don't have much experience tweaking this stuff. My setup is just a cable modem (ARRIS Surfboard) going to the 1100 going to the back of this PC. No fancy settings on the ARRIS and the 1100 is running on default settings. I just reinstalled pfsense on it via USB and updated it. I only did enough to get it working with my network connection and configured nothing beyond that.
If anyone here has any ideas or want me to try to get some information. let me know how to do that and I'll do that as soon as possible. My replies may be sporadic.
Thanks in advance for any assistance and sorry for the long post. I wanted to give as much info as possible.

Which would have zero to do with pfsense, zero!
What are you using for wifi?
So your pc is connected to pfsense via a wire.. Where are you running sweech, on your phone, a tablet? How is on this same network as your pc? You running some wifi router, an AP?

I bet he is using ARRIS surfboard wifi which will end up being on the WAN side of pfsense -

they make a gateway that is true i guess G54, or like a SBG8300 or something.. Those are not cable "modems" like he said.
But yeah putting a Layer 3 router between your L2 networks would kind of break such software ;)
Wouldn't he notice that his Ips are on different networks.. Ah his 192.168.0 vs pfsense default 192.168.1
good catch!
