IPtables configuration for different addresses? - Raspberry Pi Forums

-

i have set openvpn server on rpi3 , have configured route traffic lan via iptables.
working when connected ethernet, if connect wifi instead have change iptables commands, big hassle.
there way prepare iptables such forward traffic interface actually in use without me knowing exact address beforehand?

command have used when setting this:

code: select all

sudo iptables -t nat -a postrouting -s 10.8.0.0/24 -o eth0 -j snat --to-source 192.168.23.150
150 ip address eth0 address network, if connect wifi instead address 192.168.23.153.
, if move rpi unit other house connecting network 192.168.45.xxx instead.
soo easier if there way make work without having edit iptables settings time.

greetings.

that's why need masquerade target: http://www.iptables.info/en/iptables-ta ... radetarget

might use:
sudo iptables -t nat -a postrouting -s 10.8.0.0/24 ! -d 10.8.0.0/24 -j masquerade

"! -d" part filtering off packet going 10.8.0.0/24.

made line without test it.

SD Datastring Convention

i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...
