About NAT Table ACL Entries

To enable SIP signaling messages to reach the host processor, the Oracle® Enterprise Session Border Controller adds NAT table ACL entries for each SIP interface. With UDP without SIP port mapping applied, it adds a single ACL entry for each SIP port in the SIP interface configuration. For example:

untrusted entries:
intf:vlan source-ip/mask:port/mask dest-ip/mask:port/mask   prot type    index
0/0:0     0.0.0.0                  172.16.1.15:5060         UDP  static  10
0/3:0     0.0.0.0                  192.168.24.15:5060       UDP  static  16
0/1:0     0.0.0.0                  192.168.50.25:5060       UDP  static  17
