I have problem when i add ips to ethernet devices, have 3 ethernet and 2 adsl connections with public ips 92.***.***.188 and 92.***.***.186 , i can add one ip on eth1 but when i try to add second ip i have message
ERROR: IP 92.***.***.188/255.255.254.0 not added to ETH02 : 92.***.***.0/23 overlaps 92.***.***.0/23 (ETH01)
Yeap this is a well known issue. You cannot have IPs in the same subnet for 2 different interfaces. I has been discussed here again and the workaround was to ask your ISP to provide you the second IP from a different subnet.
