Problem when network connection is outside localnet

[wasi54]

Hi
I am using Theo Arends @arendst great tasmota software with the development version of platform-espressif8266. Some of the devices are connected via VPN over 3-5 hopps and i can not open the website of those. Ping and other network connection is working fine.
If i test the same devices on the local network, also the website can be reached. If i compile with core 2.3.0 it works also over VPN. Ist this already known? Any idea or advice to solve this issue? Additonal build flags?

Thanks in advance

I found it!
It works with

-D PIO_FRAMEWORK_ARDUINO_LWIP2_LOW_MEMORY v2 Lower Memory
or
-D PIO_FRAMEWORK_ARDUINO_LWIP2_HIGHER_BANDWIDTH v2 Higher Bandwidth

but not with:
-D PIO_FRAMEWORK_ARDUINO_LWIP_HIGHER_BANDWIDTH v1.4 Higher Bandwidth (default)
