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.

Checkpoint firewall common commands part 2

Checkpoint firewall common commands part 2 For basic firewall informaton gathering: fgate stat -Status and statistics of Flood-Gate-1. fwaccel <stat|stats|conns>  – View status, statistics or connection table of SecureXL. fw getifs -Show list of configured interfaces with IP and netmask. cpstat <app_flag> [-f flavour] -View OS, HW and CP application status. Issue cpstat without any options to see all possible application flags <app_flag> and corresponding flavours. Examples: cpstat fw -f policy – verbose policy info cpstat os -f cpu – CPU utilization statistics cpinfo -y all   -List all installed patches and hotfixes. cpd_sched_config print -Show task scheduled with CPD scheduler. enabled_blades -View enabled software blades avsu_client [-app <app>]   , get_version <app>  -Get signature version and status of content security .Without the -app option “Anti Virus” is used. show co...

Unable to Connect to Server Checkpoint R80

Unable to Connect to Server Checkpoint R80 Unable to Connect to Server A connection to the management server will fail if: A firewall between SmartConsole and the management server blocks Port 19009 -  port 19009 is used for a new R80 service. Allow traffic on this port for all clients and management servers. No GUI clients are assigned -  Open the Gaia Portal. If the First Time Configuration Wizard opens, complete it. If the First Time Configuration Wizard has already run, open  User Management > GUI Clients  and add a client. When using Multi-Domain Security Management, connect SmartConsole to the Multi-Domain Server and make sure the domains have GUI clients assigned to them. The required processes are not reachable -  Make sure the computer with SmartConsole installed can reach the IP address of the management server, and that these server processes are up and running: cpm fwm Operation time out  – Your connection ...

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...
