Configuring the Firewall and NAT:
18)
Type ‘ip access-list standard MATCHALL’ to create an access-list that will match
all traffic. This will be referenced by the NAT rule in the Private Policy-Class.
19)
Type ‘permit ip any’ to match all traffic.
20)
Type ‘exit’ to exit the access list configuration.
21)
Type ‘ip policy-class Private’ to create the Private Policy-Class. This is referenced
in the configuration of the private interface with ‘access-policy Private’.
22)
The next statement will define what Public address to use in the NAT.
a.
For non-PPP connections, where you entered the public IP Address on the
Public Ethernet Interface, type ‘nat source list MATCHALL interface
eth 0/1 overload’.
b.
For PPP connections, where you entered the public IP Address on the PPP
interface, type ‘nat source list MATCHALL interface ppp 1 overload’.
23)
Type ‘exit’ to exit the Private policy class configuration.
24)
Type ‘ip policy-class Public’ to create the Public Policy class. This policy class will
remain empty. An empty policy class denies the initiating of sessions from that
interface.
25)
Type ‘exit’ to leave the Public Policy-Class configuration.
Saving the Configuration:
It is important that you save the configuration!
26)
Type ‘end’ to return to enable mode.
27)
Type ‘write’ to permanently store the configuration on the NetVanta 2054.
Note: You can copy the output of the command “show run” into a text file and save that
file as a backup copy on your computer.
