Hello Professionals,
I'm having an weird issue with Cisco Firepower 2110, but not sure this is firepower issue or any other.
Here's what I did: (I was trying to change Firepower to PFSense firewall)
- Firepower WAN port (connects to AT&T router) : disconnect
- WAN connection connected to PFSense WAN port. Same IP address & subnet. Testing Ping/NAT.
- WAN connection move back to Firepower WAN port.
and Here's the issue:
- from LAN to WAN: working (reaching to internet)
- DMZ servers (1:1 NAT servers) are not working. Meaning, from WAN to LAN is not working.
ex) OpenVPN: 10.10.10.75 <--NAT--> 198.202.1.6
Public can't reach to openVPN over the 198.202.1.6.
There was no configuration change except I move the cable connection physically.
- Firepower WAN subnet: 198.202.1.1/28
- Ping test from OpenVPN(10.10.10.75) to 8.8.8.8 : Failed.
- During the ping to 8.8.8.8, there's no connection logs from Firepower - Connection - Event.
- packet tracer test 1.1.1.1 to 198.202.1.6 : Succeed.
Can anyone have seen this issue....?
Please help..
