I’d say running up against a 16bit number for a database import in 2025 is a little cursed. MS is special, still has a 260 path character limit (albiet soft now) in Windows.

Also with more phones taking an image and a video that is only 32767 snaps, which is probably a regular headache for initial imports.

Couldn’t stand working with people who shop at Asda!

Thats great! Overly simplistic explanation, the container is in its own little network and when you connect wireguard inside the container it is punching a hole out to where the wireguard server is located. Without knowing your setup its difficult, but that is probably why your ping is acting as it does. The container doesn’t know how to get to where you’re attempting to ping.

The allowed ips is a list, off the top of my head it accepts single IPs and cidr blocks. 0.0.0.0/0 is the cidr block that essentially means all ipv4 IPs, ::/0 is the same for ipv6. So to answer directly, the , is an or, its for any IP in the list.

Does your wireguard config have ipv6 addresses? If your not using them you can safely remove them.

For example Change AllowedIPs = 0.0.0.0/0, ::/0 To AllowedIPs = 0.0.0.0/0

Also could try adding net.ipv6.conf.all.disable_ipv6=1 in the sysctls section

Multiple edits: I’m terrible with formatting while not on a phone.

More edits: just found out i can expand errors and the compose. Looks like it is the AllowedIPs line in peer1.conf. Just removing , ::/0 as above “should” solve it
