Remove local LAN address ICE candidates
ICE candidates can contain local LAN addresses as well as external addresses. For example, here's a redacted transcript from the Snowflake JS proxy:
a=candidate:4077567720 1 udp 2122260223 192.168.1.5 51282 typ host generation 0
a=candidate:8564102000 1 udp 1686052607 X.X.X.X 51282 typ srflx raddr 192.168.1.5 rport 51282 generation 0
a=candidate:3179889176 1 tcp 1518280447 192.168.1.5 52256 typ host tcptype passive generation 0
If it's possible, we should filter them out to prevent revealing more information than necessary. Serene and I guessed that they are only there for the case when both peers are in the same local network, but we're not sure about that.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
