I'am using a RUTX11 with latest firmware.
Internet connection is done via Telekom LTE. Dual Stack IPv4/IPv6 is enabled and working.
My Client Device (raspi) is provided with a IPv6 address and ipv6-test.com is showing that address.
But I can't ping that raspi or access any services/ports provided my the raspi.
How do I need to configure the RUTX11 firewall to allow outside IPv6 traffic routed to my raspi.
