ISP has given me a Private IP for PTP(/30) and a Public IP /32 and VLAN ID. I have created a VLAN on the WAN interface and given it the Private PTP IP on the Mikrotik router. The Gateway is the ISP's Cisco Router
1) where should i put the /32 Public IP. on a cisco router this would have been a put on a loopback interface what of mikrotik
2) i am not able to ping the Gateway for the PTP /30 but it shows reachable on the routes list
what could be the issue
Cisco routers work well in the network and i know that mikrotik can do what cisco can, more the reason we want to start implementing Mikrotik on the Network

You could do much the same thing - i.e. put the /32 IP on a bridge interface and use SRC NAT on the traffic towards the ISP to use the /32 address as the source IP.

who can give reason for ping not being able to get through despite the route list showing Gateway for the private ip reachable.

Which ports should be put on the bridge interface?

You don't need any ports on the bridge for that type of use.

Do you see an ARP entry for the gateway IP address?

after activating the link my other link went down and the new route was preferred as opposed to the previous working route and shows gateway reachable.
will not show arp as the network is through and E1 link. is there a reason it would show reachable thru the VLAN Interface onto which the Private IP is configured while not able to ping.
my config for the Public IP was as below if any error confirm
chain:srcnat src address:(LAN IP Range) action:src-nat to-addresses:62.24.108.XXX out interface:VLAN
hope this is correct

It would be easier to comment if you could upload the config - output from /export compact.

r u really sure that ISP end ip is 10.2.22.74. u can try by interchanging IPs

that is what the ISP indicated and i had doubted that i had even interchanged but no result
config from a running cisco router looked like below

interface FastEthernet4.495
description UUNET Link WAN interface
encapsulation dot1Q 495
ip address 10.2.24.5 255.255.255.252
ip nat outside
ip virtual-reassembly
!
interface Vlan1
LAN Interface
ip address 192.168.1.1 255.255.255.0
ip nbar protocol-discovery
ip nat inside
ip virtual-reassembly
ip tcp adjust-mss 1430
!
ip forward-protocol nd
ip http server
no ip http secure-server
!
ip nat inside source list 103 interface loopback1090 overload
ip route 0.0.0.0 0.0.0.0 10.2.24.6


which would mean the .74 as gateway is correct
as here u see the ip on router is .5 and gateway(iso) .6

it is sorted it was an issue on the isp side

I use the same scenario for mikrotik nat loopback IPv4, the IP / Public 32 is used for NAT.

You must route the public ip over the network "/ 30" then you must make a src-nat.

This public IP / 32 you must create a bridge interface is called the IP loopback and asigar bridge.

Hi
Can you post the routing part and the src-nat part for comparison purposes, looks like it is taking a toll on the CPU of the RB750
i would really appreciate
