Subject: [PATCH] fix: removing ",gw=" from GATE variable when reading/writing
 from/to config. (#6177)

Previously when creating a config, GATE variable would incluse ",gw="
which was crashing the installer script when read later on.
This fix:
1. writes GATE variable to config without ",gw="
2. removes ",gw=" from GATE variable when reading existing config
