Hi,
I've set up a good deal of openbsd firewalls in a professional environment
before with little to no issue. I'm trying to set one up for me personally
though, and am having some bizarre issues, with no clue where to begin
trying to fix them. This is on an APU unit from PC Engines. I've managed to
figure out a couple things when trying to debug this:
1. I cannot connect to the internet properly unless only em0 (which is the
ethernet port I have connected to the external network) has a hostname
file- I have to either add back the hostname files after boot and run
/etc/netsetup or manually set up the internal network ports through
ifconfig.
2. Even once the box is connected properly to the network, its' seemingly
unable to assign leases to other clients, attempting to connect to it
through another OpenBSD machine results in it timing out while getting a
lease.
3. Using the same exact config, I ran it behind a standard proprietary
router (linksys) that connects fine externally. Using that, the box
functions as expected.
4. Using an openwrt router I get similar errors.
5. I'm using both config that I've used on external networks as well as
subnetworks on a corporate network that worked, and the default config from
the setting up a router page for a sanity check.
6. I assumed it was DHCP, but nonetheless as a sanity check I had pf pass
through anything and everything, worked internally as well as externally.
I'm at a complete loss- seeing as it occurs on openwrt I assume that its'
probably because of however the hell my landlord set up the network, but
anyone remotely have an idea how to begin debugging this? I don't like
particularly having a proprietary router running especially without a
firewall I trust.
Best,
Charlie
