3 WAN -> 1 LAN, cannot figure it out

Synackaon

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

	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.

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.
