Description iptom 2026-03-15 07:56:10 UTC 
When importing a configuration file containing multiple IP addresses,
e.g. AllowedIPs = 10.168.12.0/24, 10.168.13.0/24, 10.168.14.0/24
an error occurs 
Oops, something went wrong...

    Invalid Network 10.168.13.0/24
    Invalid Network 10.168.14.22/32

Once the spaces between the addresses have been removed,
e.g. AllowedIPs = 10.168.12.0/24,10.168.13.0/24,10.168.14.0/24 
the import proceeds without errors.

The configuration file was generated when the N2N connection was created on IPFire.

In the file `wireguard-functions.pl`, I made the recommended change shown below

# AllowedIPs
} elsif ($key eq "AllowedIPs") {
     my @networks = split(/\s*,\s*/, $val);

Following the above change, the import completed without any errors being reported.


Tested on Core-Update 203 Development Build: master/4b639c7e
