Cisco ASA 5540_outside to inside traffic NAT

Solution 1:

ok you need free ip address from your offical net x.x.55.81. on the asa in global configuration mode (conf t) you had to create a static nat from inside to outside

static (inside,outside) x.x.55.81 192.168.49.26

after that you had to allow traffic to the server on the outside interface. with the commad

show run access-group 

you get the acl name bind to the outside interface. you can allow traffic on the acl in global configuration mode for RDP access

access-list ACL-Name permit tcp any host x.x.55.81 eq 3389

or for a specified host

access-list ACL-Name permit tcp host a.b.c.d host x.x.55.81 eq 3389

or net

access-list ACL-Name permit tcp netaddress subnetmask host x.x.55.81 eq 3389
