VRRP or ClusterXL in GAIA?

VRRP or ClusterXL in GAIA?

 VRRP or ClusterXL in GAIA?

VRRP:

Pros:
1. Single virtual MAC floats between cluster members, depending on which is Master; By Default.
2. Doesn't care about CoreXL or other physical differences between cluster members. But why would you have differently sized cluster members you cheap bast**d? :)


Cons:
1. Decision is per interface.. Am I master or backup, one interface at a time; potential for split brain.
2. No Health checking of the cluster peer(s).
3. If same VRRP ID is used on all interfaces, potential to confuse switch when multiple firewall interfaces connected to same switch; multiple VLANs using same VRRP MAC.
4. Default VRRP MAC is still effected by IGMP, same as ClusterXL CCP multicast mode. VRRP hello packets are transmited using the VRRP MAC as the destination.
5. Only the Master node transmits Hello packets. No status of backup cluster member, VRRP interfaces must be monitored individually to discern if layer 2 connectivity problem exists on one or more interfaces.


ClusterXL:

Pros:
1. Health checks peer on every physical interface
2. Unified interface failover; no chance of split brain
3. Monitors policy, daemons etc.

Cons:
1. Magic Numbers(ClusterXL CCP source MACs) have to be adjusted manually when multple clusters share a VLAN/subnet, or risk instability.
2. HA New mode uses physical MAC of Active member, by default (VMAC mode now enable via R76 SmartDashboard [R76 GAIA only])


ClusterXL is more robust than VRRP in it's monitoring of peer nodes and failover. ClusterXL VMAC addresses the main problem with ClusterXL.

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...

FortiGate: Upgrading the firmware via CLI

FortiGate: Upgrading the firmware via CLI To use the following procedure, you must have a TFTP or FTP server that FortiDB can connect to. You must also log in using the “admin” administrator account. Start the FTP or TFTP server. Copy the new firmware image file to the FTP or TFTP server. Log into the CLI. Verify that FortiDB can connect to the FTP or TFTP server. For example, if the IP address of the TFTP server is 192.168.1.168, enter the CLI command: execute ping 192.168.1.168 Enter the following command to copy the firmware image from the TFTP server to FortiDB: execute restore image ftp execute restore image tftp Where is the name and location of the firmware image file and or is the IP address of the FTP or TFTP server. For example, if the firmware image file name is image.out and the IP address of the FTP or TFTP server is 192.168.1.168, enter: execute restore image tftp image.out 192.168.1.168 FortiDB responds with the message: This oper...
