3 WAN -> 1 LAN, cannot figure it out



  • Last week, we discarded our two residential connections in favor of three (3) business class cable connections from one company instead of two separate providers.

    But I cannot get load balancing to work! I hoped to make gateway group kosh work, but it doesn't.

    WAN01 - DHCP (currently 24.43.32.180), gateway 24.43.32.129 {wan}, Virtual IP 19.0.0.1/24
    WAN02 - DHCP (currently 24.43.32.145), gateway 24.43.32.129 {opt1}, Virtual IP 18.0.0.1/24
    WAN03 -DHCP (currently 24.43.32.143) ,gateway 24.43.32.129  {opt2}, Virtual IP 17.0.0.1/24

    My firewall rules are:

    
       	ID  	Proto  	Source  	Port  	Destination  	Port  	Gateway  	Queue  	Schedule  	Description  	
     		* 		LAN net 	* 	169.0.1.0/24 		* 		* 		none 	  	  	
     		* 		LAN net 	* 	169.0.2.0/24 		* 		* 		none 	  	  	
     		* 		LAN net 	* 	169.0.3.0/24 		* 		* 		none 	  	  
    
    
    
     	   	ID  	Proto  	Source  	Port  	Destination  	Port  	Gateway  	Queue  	Schedule  	Description  	
     		* 	LAN net 	*	 	* 		*	 	* 	none 	  	Default allow LAN to any rule 
    
    

    I have a gateway group, kosh:

    
    Group Name  	Gateways  	Priority  	Description  	
    	kosh	 	GW_WAN	Tier 1
    			GW_OPT1	Tier 1
    			GW_OPT2	Tier 1
    
    
    
    Name  	Interface  	Gateway  	Monitor IP  	Description  	
    
    GW_WAN 	WAN1 	dynamic 	24.43.32.129 	Interface wan dynamic gateway  	
    GW_OPT1 	WAN2 	dynamic 	24.43.32.129 	Interface opt1 dynamic gateway  	
    GW_OPT2 	WAN3 	dynamic 	24.43.32.129 	Interface opt2 dynamic gateway
    
    
    
    Interface  	Source  	Source Port  	Destination  	Destination Port  	NAT Address  	NAT Port  	Static Port  	Description  	
    	WAN   	any 		* 		169.0.1.0/24 	*		 	169.0.1.1 		* 	NO	wan1 out  	
    	WAN2   	any 		* 		169.0.2.0/24 	* 			169.0.2.1 		* 	NO	wan2 out  	
    	WAN3   	any 		* 		169.0.3.0/24 	*		 	169.0.3.1 		* 	NO	wan3 out  	
    	WAN   	any 		* 		* 			*	 		*		 	* 	NO	wan1 out default  	
    	WAN2   	any 		* 		* 			* 			* 			* 	NO	wan2 out default  	
    	WAN3   	any 		* 		* 			* 			* 			* 	NO	wan3 out default  
    
    


  • You can't have 3 WANs with the same gateway, each gateway must be unique.



  • @cmb:

    You can't have 3 WANs with the same gateway, each gateway must be unique.

    While this is understandable, given it's Layer 3, but is it possible to do this on Layer 2?

    I know you could try to use LAGG I suppose for connections of equal bandwidth, but doesn't 'feel right' - is there any way that apinger can be configured to be interface-centric instead of gateway-centric?



  • Its a routing problem not an apinger one.

    Sorry I was digressing the topic.

    I was asking whether load balancing be achieved at Layer 2 (ie MAC addresses/interfaces) instead of Layer 3 (ie IP addresses and gateways), without using LAGG?

    No. Since it's going to be the same MAC, it's unpredictable which interface will see it first.
