In **Core-Update 198** IPsec tunnel settings there is a Remote subnet option.

In **Core-Update 200 IPsec** tunnel this field is missing???

It is replaced by a DNS Servers field… (The remote subnet field is gone !!)

Where can I configure the remote Subnet for an IPsec tunnel ?

thanks,

Leo

You need to select the entry for a Net to Net tunnel

then when you press the add button you will get

The entry with DNS Servers is when you select Host to Net (Roadwarrior)
