Hi,
We’re using Cisco ASA 5520.
I have set-up the following interface
outside: 172.20.55.240 (security:0)
zone1: 192.10.10.1 (security: 100)
i have a server 192.10.10.21 that I need to allow external DNS access
I have a static NAT
source: 192.10.10.21
NAT: 172.20.55.240
service 53 (TCP and UDP)
and FW rule
allow source 192.10.10.21 to any for service 53 (TCP and UDP)
however this is not working.
Are there more configuration required?
thanks!
