Subnet Group
Using a Subnet policy group, you can automatically select a policy based on the current network environment. You can use subnet expression as a condition.
Subnet Group = subnet, default = ProxyHTTP, TYPE:WIFI = ProxyHTTP, SSID:MyHome = ProxySOCKS5
Starting from Surge iOS 4.12.0 & Surge Mac 4.5.0, the SSID group is now renamed to Subnet Group.
The legacy syntax of SSID Group is still supported. You may use the group type keyword subnet or ssid for compatibility.
Parameters
default: Required
The policy when no subnet expression is matched.
cellular: Optional (Deprecated, use TYPE:CELLULAR instead)
The policy for cellular networks. If not provided, the default policy will be used.
