hello to all,
I have the existing setup:
ipfire core on a raspi model 3b+
red pppoe wan
green lan 192.168.31.0/24
blue wlan 192.168.10.0/24
OpenVPN server with occasionally maximum 2 clients!
My existing bandwidth is 11/100 Mbps but I only get 11/75 Mbps(1km from ISP’s cabin)!
I also have some firewall rules for allowing OpenVPN connections to my network and geolocation blocking as well!
The overall experience so far(running this 24/7 for somewhat 1 year now!) is very smooth and never have encountered disconnections/delays/random restarts neither to my bandwidth nor to the ipfire server!! Also I have IPS with Emerging Threats Community Ruleset running only on Green.
The hardware monitoring is showing that even at the high peaks of the day the memory/CPU bandwidth is more than enough!!!
So the problems that I have is these:
with the default wireless card of the pi, the blue network acts slow(logical) and also because I run captive portal with disclaimers, the redirect sometimes never happens. The weirdest is that most of the times the “blue” clients don’t receive ip from the DCHP server that I, of course run and have set it up! Even if I plug a network usb adapter like a TP-LINK tl-wn721n the same things seems to occur!
Is there something that I missing OR maybe the TP-LINK is uncapable for acting as an AP ?
I need to connect a USB 3G stick to one of the ports to make a High Availability in case that my primary red wan connection fails(i run also a DAHUA NVR on the network and an IP alarm system so that is the need for)! I already saw the compatible modems list here wiki.ipfire.org - Network Adapter Hardware Compatibility List but because I don’t have pci slots on my pi that is
not an option for me! I have one 3g modem stick from Vodafone that when I connect to my raspi via USB this strange thing happens…
The connection on wan gets dropped(all clients lose connection to the internet) and also the entire ipfire server is inaccessible(ssh/https)!
So I cannot really tell/see what is happening as I have the raspi headless. The green led on the USB flashes as normal though! The logical consumption here is that this USB 3g modem is NOT compatible and that is OK but why the ipfire seems to reroute everything through this?
Is it maybe a settings problem that I need to have preconfigured(you are able to access its webface from a windows machine) on my USB modem before I try to connect it in my raspi?
Also is it better to, maybe buy a 3g/4g modem that has a wan port on it and maybe bridge that to a usb 3.0 ethernet adapter? (I would like to avoid that if I could and make it through a USB modem directly!!!)
Please forgive if here is not the appropriate section but I’m totally new to the forum!
