So this is an interesting one I can't figure out myself. I have Proxmox on a PowerEdge R730 with 5 NICs (4 + management). The management interface is doing its own thing so don't worry about that. Currently I have all 4 other interfaces bonded and bridged to a single IP. This IP is for my internal network (192.168.1.0/24, VLAN 1). This has been working great. I have no issues with any containers on this network. One of those containers happens to be one of two FreeIPA replicas, the other living in the cloud. I have had no issues using DNS or anything else for FreeIPA from this internal network nor from my cloud network or VPN networks.
Now, I finally have some stuff I want to toss in my DMZ network (192.168.5.0/24, VLAN 5) and so I'll just use my nice R730 to do so, right? Nope! I can get internet, I can even use the DNS server normally, but the second I go near my FreeIPA domains it all falls apart. For instance, I can get the records for example.local just fine, but the second i request ipa.example.local or ds.ipa.example.local, i get EDE 22: No Reachable Authority. This is despite the server that's being requested from being the authority for this zone. I can query the same internal DNS server from either the same internal network or a different network and it works handy dandy, but not from the R730 on another network. I can't even see the NS glue records on my public DNS root server.
I'm honestly not sure why everything except these FreeIPA domains works. Yes, I have the firewall open for it and I have added a trusted_networks
ACL to Bind and allowed queries, recursion, and query_cache for this ACL. The fact it only breaks on these FreeIPA subdomains makes me think it's a forwarding issue, but shouldn't it see the NS records and keep going? It can ping all the addresses that might come up from DNS, it's showing the same SOA when I query the root domain, it just refuses to work from my IPA domains. Can someone provide any insight on this please, I'm sick and tired of trying to debug it.
space might not cool it down because the only real way for it to lose the heat would be blackbody radiation. by now it's probably cooled off but without any atmosphere or other materials to cool it off, it probably stayed hot for a while
