After using IPFire for a few years, I suddenly encounter the problem of my server in Orange/DMZ not being able to access updates via RED. The only change was removing a router on red, so IPFire is now connected to a public IP:
orange: 10.0.0.10 <-> 10.0.01 IPFIRE Orange <-> IPFire RED 80.X.Y.Z → Public Internet
Orange has a default gateway of 10.0.0.1 and can ping the Red Interface (and any other IPFire Interface).
The IPFire Server can access the internet.
- without a rule for orange to red
- with a rule orange to red allow any protocol without NAT
- with a rule orange to red allow any protocol with source NAT
None of them worked. I can not ping to targets outside of orange and green.
It is not a DNS issue causing it, I tried to ping a public IP which should respond.
Does anybody have a hint what problem I am not seeing?
The environment is:
IPFire 2.19 (x86_64) - Core Update 116
