PostUp Script truncated

[lfstuttgart]

Situation

The PostUp Script gets truncated - probably while it is written to wireguard-ui's database

This results in the following error during Wireguard startup:

Dec 18 06:07:02 wireguard wg-quick[133303]: [#] nft add table ip filter; nft add chain ip filter forward { type filter hook forward priority 0 \; }; nft add rule ip fil> Dec 18 06:07:02 wireguard wg-quick[133366]: Error: syntax error, unexpected newline Dec 18 06:07:02 wireguard wg-quick[133366]: add rule ip filter forward iif Dec 18 06:07:02 wireguard wg-quick[133366]: ^ Dec 18 06:07:02 wireguard wg-quick[133303]: [#] ip link delete dev wg0

Our PostUp Script
nft add table ip filter; nft add chain ip filter forward { type filter hook forward priority 0 \; }; nft add rule ip filter forward iif "wg0" accept; nft add table ip nat; nft add chain ip nat postrouting { type nat hook postrouting priority 100 \; }; nft add rule ip nat postrouting oif "eth0" masquerade

Reproduce

1. in Wireguard-UI go to Wireguard Server page page a longer PostUp Script like the above and click Save.
2. Go to another page - for example Wireguard Clients.
3. Go back to Wireguard Server page
4. Click Apply Config

If your check the config file for on the server now, the PostUp script is truncated.
