There are three interfaces, TRUST (security level 100), UNTRUST (security level 0), and DMZ (security level 50).
I am on a network coming into the firewall via the UNTRUST interface. The switch I am able to use ICMP with but not SSH to (timeout) is connected via the DMZ interface. There are three rules which each included the same service group (including icmp, tcp/ssh, udp/tftp, tcp/telnet, udp/syslog). These rules are applied as follows:
DMZ Interface (incoming)
DMZ_network any IP permit
TRUST Interface (incoming)
DMZ_switch my_laptop service_group permit
UNTRUST Interface (incoming)
my_laptop DMZ_switch service_group permit
So I am able to ICMP, and I see increment on the rules that have been applied, but I receive connection-timeout for SSH connection attempts. I've spent too much time hitting my head on the proverbial wall to not reach out for an assist here. I appreciate anyone and everyone who takes time to read or answer this question.
