Hi !
First question : How did you get the ip and save it into config.txt ?
EDIT :
If I presume that you get the IP from the command line ARP -A in the first line
You can do something like that without using the config.txt
--- Code: ---@echo off
Title Change VPN Settings
for /f "tokens=2" %%a in ('arp -a ^| findstr /i "\<Interface\>"') do set IP=%%a
echo The IP address is %IP%
pause
ECHO Configuring Proxy Settings please wait...
ECHO REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1 /f
ECHO REG ADD "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d %IP%:8080 /f
pause
--- End code ---
Note : I added the command ECHO To be sure if the IP is correct, then you can remove every ECHO before the command REG ADD

thanks dear Hackoo
your cod is working but i am using vpn from my mobile phone for my laptop pc so
i get my new ip in this way
--- Quote ---@echo off
REM clear arp cache (optional):
arp -d
REM ask everybody on the subnet for a response:
for /l %%a in (1,1,255) do start /b ping -n 2 -w 500 192.168.1.%%a >nul
REM wait for the processes to finish:
timeout 2 >nul
REM show the responses (with IP and MAC):
arp -a>mynew-ip.txt
pause
--- End quote ---
in mynew-ip.txt i have this
--- Code: ---Interface: 192.168.11.181 --- 0xc
Internet Address Physical Address Type
192.168.11.49 4e-53-d0-68-34-bf dynamic
--- End code ---
192.168.11.49==== is my new working ip that i need every day so you should use this ip in your cod
mioo_sara:
if its complicated and time consuming just answer my question in first post of this topic and i will solve the other parts with external aps automatically
just replace first line ip in post #1 with old ip in 5th line
thanks
Hackoo:
Give a try for this code, and tell me how it works on your side ?
--- Code: ---@echo off
for /f "tokens=1" %%a in ('findstr "192.168.11." mynew-ip.txt') do set IP=%%a
echo The new working IP is %IP%
pause
