I am having an issue with my Cisco ASA and SophosUTM device.
I have had the SophosUTM installed as a VM for several months now and it has worked without any issues, I have now moved to the hardware appliance and this is when this problem has come from.
Basically I am trying to cross from my 'Inside' interface over to the 'DMZ' interface to access the user management web portal, This is not working and it looks to be the ASA causing the issues. (I can connect to other sites running in the DMZ.)
- Was working as a VM on Esxi host
- Now plugged directly into the Switch (Tried to tag ports as Lan, Dmz & Trunk (Same as Vmware)
- On the Sophos it is setup as Ethernet with Vlan tagging and has the DMZ vlan id set
- Can pint the device with the DMZ IP from 'Inside' interface, just cant connect to HTTPS.
- UTM can see the traffic from my IP for https and is allowing it
I can see from the Reset-I its being closed from the interface inside and looks to be from the UTM but I just dont understand why?
Any help is resolving would be of great help or anyway to produce any more tracing to see what's actually going on here.
Thanks,
Rob
