I'm trying to access a SuperMicro IPMI card that is behind an OpenBSD bridged firewall.
A couple pieces of information:
- The OpenBSD firewall itself has a SuperMicro IPMI that I can access across the internet.
- The IPMI I'm trying to reach can be reached from behind the firewall.
My gateway does arp request the IPMI and it does appear to respond (this is from the external interface of the firewall)
16:57:45.548892 arp who-has ipminame tell gwname16:57:45.549500 arp reply ipminame is-at ipmimac
But when I make a request to the IPMI IP from outside the firewall the external interface of the firewall shows no traffic with the IPMI ip as its destination.
Any idea what might be causing this problem? Is there something about IPMI traffic that my gateway wouldn't like (the gateway is provided by my colocation provider so I can't easily debug it).
