Subnet Group
Using a subnet policy group, you can automatically select a policy based on the current network environment. You can use subnet expressions as conditions.
Subnet Group = subnet, default = ProxyHTTP, TYPE:WIFI = ProxyHTTP, SSID:MyHome = ProxySOCKS5
Starting from Surge iOS 4.12.0 and Surge Mac 4.5.0, the SSID group was renamed to Subnet Group.
The legacy SSID Group syntax 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 it is not provided, the default policy is used.
