Good day!
I can change network interfaces and do port forwarding on your Turris router with OpenWRT firmware efficiently and quickly because I am a certified network engineer (MTCIPv6E / MTCTCE/ MTCNA) having over 10 years of experience with configuration, maintenance, and troubleshooting of enterprise network devices, firewalls, and Linux servers (including routers with DD-WRT and OpenWRT firmware).
This can be done using a web-interface (LuCi) or command-line interface (shell with iptables).
