[strongSwan] IPSec Tunnel IP

[Yusuf Güngör]

Hi,

I have a configuration like below and VPN connection successfully
established but client side get "1.1.1.127" as tunnel IP. Can we change
this tunnel IP? I can not find any clue about why StrongSwan assign
"1.1.1.127" as tunnel IP to clients?

Thanks.
