XG115w_XN03_SFOS 17.5.0 GA
Port2 wan = isp1 with gateway active
Port4 wan = isp2 with gateway active
RED client interface selects Port2 for its traffic automatically - I think the selection is always based on the lowest numbered active wan interface for RED and I haven't found a way to control its selection other than recabling isp's or changing wan interface gateways from active to backup which impacts load balancing options in an unwanted way.
Lan >> wan firewall rule = primary gateway is isp2 , backup gateway is isp1
In this dual wan setup what is the correct approach to force XG initiated wan traffic such as pattern/firmware updates, Sophos communications, and console network diagnostics to use isp2 on the Port4 interface without impacting lan >> wan traffic failover or the RED client physical interface selection? What is the XG's method of selecting where it sends XG initiated wan traffic? Adding a static route to direct a given wan destination to a set isp does work for XG initiated traffic but also takes precedence over the firewall rule which is unwanted for lan to wan traffic given that static route failover functionality is lacking (https://community.sophos.com/kb/en-us/123611) A route added in the network >> policy routing screen seems to have no effect on XG initiated traffic or is lower precedence behind something else acting on the traffic. Thanks for any suggestions.
