Hello,

Have inherited an ASA5510 and need some assistance.  Just had an NEC VOIP phone system installed and we have a single IP phone that is going to a remote site that needs UDP access through the ASA public IP > a pair of internal IP's based on port.  I'm not familiar how to do this.  Here is what I have so far:

object network nec1100_cpu
 host 192.168.0.201

obect network nec1100_cpu_out
 host <public IP>

object-group service nec1100_cpu_ports
 description Inbound ports needed for VOIP Registration
 service-object udp destination eq 5060
 service-object udp destination range 5080 5081

access-list outside_access_in extended permit object-group nec11_cpu_ports any object nec1100_cpu

object network nec1100_cpu
 nat (inside,outside) static <public IP>

object network network nec1100_cpu_out
 nat (outside,inside) static 192.168.0.201

 

Now I need to add UDP forwarding for 10020-10083 from the same <public IP> to internal IP 192.168.0.202.  How to accomplish this?

Thanks in advance!

Read the above article. You need to use PAT, which will involve defining all of the ports that will be forwarded as part of the network object. You may need multiple network objects per real inside IP.
