Problem to ping Internet with 2 Public IP in different range

RouterOS Beginner Basics
1

Hi friends ,

I have this scenario and I cannot ping the Internet URL or any IPs out of my network

Mikrotik : RouterOS v 3.2
VMware server on Windows server 2003 and the ether1 is in bridge mode.

Server : IP 72.35.115.113/29 and IP: 72.35.111.186/27
Gateway: 72.35.111.161

Avaiable IP : 72.35.115.114-118 /29

Mikrotik: IP:72.35.115.114/29 and Gateway: 72.35.115.113 ( I can put 72.35.111.186 as well but the same problem)

I didn’t add 2nd Ethernet to my Mikrotik RouterOS but I have 2 Vms in my Server2003.
Vm1: 192.168.61.1 ( Host)
Vm8: 192.168.80.1 ( NAT)

Problem : Cannot ping IPs out of my network , in other word RouterOS doesn’t have any connection to internet.

Why? Because I have 2 different IPs range and only 1 IP is in the range of my server 2003 Gateway (72.35.111.161)
(If I have had 2nd IP in the same range of Server 2003 gateway (ex: 72.35.111.187/27) , it would work fine, but I don’t have this 2nd IP)

Question : How can I configure the router to be able to ping the IPs out my network, for this scenario?


I appreciate for any suggestion and helps.

Cheers

Did you remember to srcnat or masquerade your private IPs to a public IP? If you need assistance, please post the output of:
/ip firewall nat print

Hi SurferTim,

Thank you for your quick reply. This is all my setting and didn't set any Firewall NAT.

Maybe you can tell me how configure the router to be able to ping the internet.

I set 2 IP addresses for my Physical NIC in windows 2003
70.35.111.186/27 with Gateway 70.35.111.161
70.35.115.113/29

I configured Ethernet card for VMware as bridge (vm0) and this is the config of Mikrotik

ip address print

ADDRESS NETWORK BROADCAST INTERFACE

0 70.35.115.114/29 70.35.115.112 70.35.115.119 ether1

ip route print

DST-ADDRESS PREF-SRC G GATEWAY DISTANCE INTERFACE

1 A S 0.0.0.0/0 r 70.38.117.113 1 ether1
2 ADC 70.38.117.112/29 70.38.117.114 0 ether1

I did following tests:

[admin@MikroTik] > ping 70.35.115.113
70.35.115.113 64 byte ping: ttl=128 time<1 ms

[admin@MikroTik] > ping 70.35.111.186
70.35.111.186 64 byte ping: ttl=128 time<1 ms

[admin@MikroTik] > ping 70.35.111.161
70.35.111.161 ping timeout

[admin@MikroTik] > ping 4.2.2.4
4.2.2.4 ping timeout

I cannot ping internet IPs and the default gateway. I have another Router with IPs in the same rage and works fine. But with this router and 2 IP in different range I have problem. For sure I missed something for this special case.

Any suggestion and help would be appreciated.

Many thanks
