Tring to add a new static nat rules, but it seems that i an not able to do that
10.10.10.10 Public IP
20.20.20.20 inside LAN IP
trying to add:
fw(config)# static (inside,outside) tcp 10.10.10.10 https 20.20.20.20 https netmask 255.255.255.255
ERROR: mapped-address conflict with existing static
inside:20.20.20.20 to outside:10.10.10.10 netmask 255.255.255.255
The rule with the same public IP existing already but pointing to the diffrent Internal LAN IP:
static (inside,outside) 10.10.10.10 20.20.20.21 netmask 255.255.255.255
Please advice how to solve this.
Thanks!

Hi Vucko,
Please change your existing static-nat to a particular port instead of leave it as ip-to-ip nat.
"static (inside,outside) 10.10.10.10 20.20.20.21 netmask 255.255.255.255"
And then you can add second static nat to different IP (i.e inside ip) and it will take it and it should work.
thanks
