Banana Pi R2 - wifi hotspot - best practices

[vobo70]

Hello,

I have Banana Pi R2 with armbian bionic. Have two wlan cards both USB, both works. 

But earlier when I used openwrt on x86 my both wlan and lan were bridged and had one IP - which was router IP.

Here with armbian wlan hotspot get other IP than armbian itself. Is there any way to change it to bridge?
Or best practices is to leave it as is?

regards,

Maciek

For hotspots, there are 3 modes :
Bridge : Wifi IP address are in same range as your network and it's your DHCP deliver wifi IP address
Routing : Wifi IP address are not in the same range as your network, wifi IP address are deliver per the hotspot ; your network must be "informed" the range IP of wifi ( routing table )
NAT : The wifi is full managed per the hotspot ; on your network you see only connection initiated per the hotspot
Each mode have advantages and inconvenient, that depending your wifi using

We used to have both, but maintaining both become too much when there is little help ... I would like to see both + some basic firewall config, but don't know when

I done some thing no bad on my 2 hotspot in routing mode with a script to manage IPTABLES rules

The script firewall_rules.sh in /etc/init.d/ load pre-defined rules in /etc/firewall.d/

firewall_rules.sh

Here a small set of rules i use with the precedent script

Rule can be easy enable and disable with set or reset executable status off file rule

I think with my firewall script it is possible to do different set of rules ( Bridge, Routing, NAT ) can be enable according to desired mode

[Igor]

.... first a bridge mode has to be enables back, solve problems, test, test, test implement your ruleset with possible adjustments and test, test, test.

 

I am unable to make big changes ATM. Can only review at best.

I don't understand the mounting/mapping/bridging of ethernet ports on Banana Pi R2 : eth0, br0, wan, lan1-2-3-4
br0 is the bridge but in eth0, br0, wan, lan1-2-3-4 what is physical interface or logical interface ?

Does anyone know or tested if this WiFi card Compex WLE600VX  Mini PCIe Module QCA9882 802.11AC 867Mbps can use used on the Banana Pi R2 device ?

Here on the Armbian page for BananaPi R2 https://www.armbian.com/bananapi-r2/ I see an image with this card inserted into the mPCIE slot but I do not find any other information related to it.

I tested it. It worked - on our images which are sadly not supported for this board. No time / resources to proceed. If wireless module doesn't show up, you only need to install firmware, probably

apt install armbian-firmware-full

will do.

Thanks for information. I have ordered one piece of this wifi card.
