Configuring Proxy ARP for Manual NAT

Configuring Proxy ARP for Manual NAT Symptoms After creating a Manual Static NAT rule, Security Gateway does not answer the ARP Requests for the Static NATed IP address that was configured in the Manual NAT rule. Security Gateway replies to ARP requests with a wrong MAC address, mostly for the NAT traffic. Introduction Let us consider the following scenario: Two networks ( Network_A and Network_B ) are separated by a Security Gateway (single Security Gateway or ClusterXL). On each network, there is a host ( Host_A on Network_A , Host_B on Network_B ). Let us assume, that Network_A represents the Internal network, and Network_B represents the External network. According to the existing standards, when Host_B needs to send data to Host_A , an ARP Request for the MAC address of Host_A will be sent by Host_B to Network...

How to modify SSH/HTTP/Telnet time out in Cisco ASA firewall?

How to modify SSH/HTTP/Telnet time out in Cisco ASA firewall? By default tcp idle timeout is 1:0:0 hh:mm:ss. If in case you need to modify it you can do it by MPF (Modular Policy Framework). Let us setup a custom timeout when traffic is coming from particular host 10.77.241.129. !— Match the traffic using the access-list —! object-group service DM_INLINE_TCP_1 tcp port-object eq www port-object eq ssh port-object eq telnet access-list outside_mpc extended permit tcp host 10.77.241.129 <source ip> any object-group DM_INLINE_TCP_1 !— Define the class map Cisco-class –! class-map Cisco-class match access-list outside_mpc !— Call this class-map into policy map and set the connection reset after 10 min when traffic is coming from particular host —! policy-map Cisco-policy class Cisco-class set connection timeout idle 0:10:00 reset !— Apply the policy-map Cisco-policy on the interface. —! service-policy Cisco-p...
