i have problem with brigde and real ip
network is 10.15.xx.xxx/30 mt wan interface and modem telindus 1421 (10.15.xx.xxx)
85.30.xx.xxx/29 my real ip

need client to work with real ip 85.30…

setup the mikrotik
give that command in router
/ interface bridge add name=“bridge1” mtu=1500 arp=enabled stp=yes priority=32768 ageing-time=5m forward-delay=15s garbage-collection-interval=5s hello-time=2s max-message-age=20s
/interface bridge port add bridge=bridge1 interface=ether1
/interface bridge port add bridge=bridge1 interface=ether2
/ip address add address=10.15.xx.xxx/30 interface=bridge1
/ip address add address=85.30.xx.xxx/29 interface=bridge1
now connect to mikrotik with winbox and give the licence
setup the gateway 10.15.xx.xxx interface bridge1
next step setup dns from my provider 82.197.xx.x -82.197.xx.x

after that mikrotik dont ping the gateway 10.15.xx.xxx (telindus 1421)

have internet only if nat enable with that command
/ip firewall nat add chain=srcnat action=masquerade out-interface=bridge1
but not need nat
need only my real ip work without nat or alias

what is wrong???

/ip address add address=10.15.xx.xxx/30 interface=public
/ip address add address=85.30.xx.xxx/29 interface=private
