ip firewall
Use the ip firewall command to enable ADTRAN OS security features including access control policies
and lists, Network Address Translation (NAT), and the stateful inspection firewall. Use the no form of this
command to disable the security functionality.
Disabling the ADTRAN OS security features (using the no ip firewall command) does not
affect security configuration. All configuration parameters will remain intact, but no
security data processing will be attempted.
For information regarding the use of OSPF with ip firewall enabled, see the Functional
Note for router ospf on page 227.
For information regarding the use of IKE negotiation for VPN with ip firewall enabled,
see the Functional Note for the command crypto map <mapname> on page 301.
