Hello, 
 when you "add" 2 WAN lines, you will have three uplinks, then? Is this correct? 
 What do you want to achieve with "load balancing"? Please describe your use case.

Hello, 
 now I understand better. If using additional uplinks, you always need to cable both HA devices identically. So you have to use another switch where you plug in both cables from the Sophos firewall and the uplink running to your ISP-router. If you have three uplinks, use three switches or configure VLANs, one VLAN for each uplink-group. 
 But please answer my second question: What do you want to achieve with "load balancing"? Please describe your use case. 
 I would like to know, if you mean load balancing an internal (web)-server behind the firewall, then you should use the WAF-module. 
 If you your intention is to have more bandwidth for internet downloads and uploads, use multipath rules. 
 If you want to have a failover possibilty with two or more uplinks from differnet providers, to have a resilient connection, then you just configure uplink balancing. 
 And so on... 
 You see, we have to guess here, because you didn't give us a clue about your use case. 
 Please try to describe your intentions a little bit more in detail.
