I have continue testing and i can set manually ip address on Windows but server assign any from dhcp pool
Mar 11 00:04:25 900333e2e8f1 charon[29393]: 12[IKE] peer requested virtual IP 10.8.0.112
Mar 11 00:04:25 900333e2e8f1 charon[29393]: 12[CFG] assigning new lease to 'dottas'
Mar 11 00:04:25 900333e2e8f1 charon[29393]: 12[IKE] assigning virtual IP 10.8.0.1 to peer 'dottas'
Is possible force to use requested virtual IP?
Thanks
