Problem you are trying to solve

I'm facing an issue in simplewall where custom user rules to allow LAN traffic (e.g., UDP/IGMP on local IPs like 192.168.50.x) are overridden by internal blacklist rules like Internal\BlockRecvAccept and Internal\BlockConnection, even when user rules are prioritized at the top and include addresses such as 192.168.50.0/24;224.0.0.0/4 for multicast. Attempts to use app-specific rules, enable system rules for services like mDNS/IGMP, or add a lower-priority block for non-LAN IPs don't work, forcing disabling internals as a workaround, which reduces security.
Cannot enable LAN bypass, no matter what I do, I simply cannot make a LAN bypass.

Suggested solution

Allowing a user rule list to override any and all blocklists.
OR
Add a whitelist builded in that enables all LAN communications.
