This is my loopback X.X.X.62/32 configured on my router.

I am trying to ping this loopback from 70.x.x.52 this is one of public IP, I want to allow ping to this IP.

Please advise what am I missing or what need to be done to achieve this.

Thanks.

Hello,

post the full configuration of your router, or at the very least indicate which access lists are applied to the interface with the public IP address and the loopback interface...

Beast6 · ‎04-04-2019

I have posted the full configuration below. Please advise.

Thanks

Source 70.x.x.52-public IP.

200.20.20.x,200.20.21.x,200.20.22.x - these are my remote sites which are nated inside with a public IP assigned. Each remote has own public IP. These pool of public IP's are given to us to manage ourselves.

In these public IP's X.X.X.62 is one of those, I have a request from the customer that he want to ping the public IP assigned to that remote from a monitoring tool which as public IO 70.x.x.52 so he can know that site is up or not.

Remote 200.20.21.142 - assigned public X.X.X.62.

We manage the public's so I mentioned it as loopback and I able to ping the IP from remote 200.20.21.142 but I want to allow ICMP to the requested public IP 70.x.x.52 for the customer.

Please advise and let me know if need more information.

Thanks.

Hello

your term of public ip is rather confusing- basically am I correct in that what you are requiring is for that loopback6 address to be icmp reachable from outside your nat boundary?

Please rate and mark as an accepted solution if you have found any of the information provided useful.
This then could assist others on these forums to find a valuable answer and broadens the community’s global network.

Kind Regards
Paul

Beast6 · ‎04-04-2019

Yes, you are right. I want ICMP for that loopback from an outside public which is not in my nat boundary.

For example, I want ICMP from this IP 209.163.240.162 to my loopback6.

Thanks.

Richard Burts · ‎04-04-2019

Thanks for the clarification. It is difficult to know what is going on when you describe x.x.x.62. Is this a public address? Or is this some private address? This is significant in determining whether address translation is required. Since I see that your config does have address translation for the address I am assuming that nat is required.

ip nat inside source static tcp 200.20.21.142 port3 X.X.X.62 port3 extendable
ip nat inside source static tcp 200.20.21.142 port4 X.X.X.62 port4 extendable
ip nat inside source static tcp 200.20.21.142 port5 X.X.X.62 port5 extendable
ip nat inside source static udp 200.20.21.142 port5 X.X.X.62 port5 extendable
ip nat inside source static tcp 200.20.21.142 37777 X.X.X.62 37777 extendable
ip nat inside source static tcp 200.20.21.142 37778 X.X.X.62 37778 extendable
ip nat inside source static udp 200.20.21.142 37778 X.X.X.62 37778 extendable

The issue is that you are providing translation for some ports (and it is difficult to understand which ports it really is) but not providing translation of ICMP. If you want ping to work then you need to provide a translation for ICMP.

Hello

Just like to add, loopback6 would also require to be a member of a security zone and some of the acl amended.

Possible example:

interface Loopback6
zone-member security E_FW_INSIDE_ZONE

ip access-list extended E_FW_SLF_TO_INSIDE_ACL_05
permit icmp host X.X.X.62 any

ip access-list extended E_FW_OUTSIDE_TO_SLF_ACL_04
permit ip host 70.x.x.52 any
permit icmp host 70.x.x.52 any

ip access-list extended E_FW_INSIDE_TO_SLF_ACL_02
permit icmp any host X.X.X.62

access-list 100 permit icmp host X.X.X.62 host 70.x.x.52
access-list 100 permit icmp host 70.x.x.52 any

route-map ICMP
match ip address 100

ip nat inside source static X.X.X.62 X.X.X.4 route-map ICMP extendable

Please rate and mark as an accepted solution if you have found any of the information provided useful.

Hi paul,

I tried the example you mentioned but it didn't work.

Thanks.

Beast6 · ‎04-05-2019

Yes- X.X.X.62 is a public IP address.

So we nat inside our remote site IP with this assigned public IP, as you can see my remote is 200.20.21.142 and assigned public IP X.X.X.62.

Before I was not able to ping the public IP from remote so I created loopback6 and set rules to permit ICMP and it worked. Now I can ping public IP X.X.X.62 from the remote 200.20.21.142.

What needs to be added if I want to ping the public IP loopback6 from any desired Outside public IP.

Thanks.

Hello,

not wanting to be redundant, I have been reading through this thread.

I would agree with Paul that in order to reach the Loopback6 IP address from any outside public IP address, the loopback interface needs to become part of the ZBF. I have tested below configuration in GNS3. In order not to interfere with the existing inside zones, I have added an extra security zone just for the Loopback

interface Loopback6
ip address X.X.X.62 255.255.255.255

zone-member security DMZ_LOOPBACK
!

class-map type inspect match-all ICMP_OUT_TO_DMZ_CLASS
match access-group name ICMP_OUT_TO_DMZ_ACL
!
policy-map type inspect ICMP_OUT_TO_DMZ_POLICY
class type inspect ICMP_OUT_TO_DMZ_CLASS
pass
class class-default
drop
!
zone security DMZ_LOOPBACK
zone security E_FW_OUTSIDE_ZONE
zone-pair security ICMP_OUT_TO_DMZ source E_FW_OUTSIDE_ZONE destination DMZ_LOOPBACK
service-policy type inspect ICMP_OUT_TO_DMZ_POLICY
!
ip access-list extended ICMP_OUT_TO_DMZ_ACL
permit icmp any host 10.10.10.62

Is the IP address of Loopback6 the same as the IP address used in your static NAT entries ?

interface Loopback6
ip address X.X.X.62 255.255.255.255

ip nat inside source static tcp 200.20.21.142 554 X.X.X.62 554 extendable
ip nat inside source static tcp 200.20.21.142 9200 X.X.X.62 9200 extendable
ip nat inside source static tcp 200.20.21.142 22609 X.X.X.62 22609 extendable
ip nat inside source static udp 200.20.21.142 22609 X.X.X.62 22609 extendable
ip nat inside source static tcp 200.20.21.142 37777 X.X.X.62 37777 extendable
ip nat inside source static tcp 200.20.21.142 37778 X.X.X.62 37778 extendable
ip nat inside source static udp 200.20.21.142 37778 X.X.X.62 37778 extendable

Your static routes point to a NAT inside interface, so I guess your customers are not connected through the outside, through the public Internet ?

ip route 200.20.20.0 255.255.255.0 10.10.2.1
ip route 200.20.21.0 255.255.255.0 10.10.2.1
ip route 200.20.22.0 255.255.255.0 10.10.2.1

In short, I think it would be helpful if you provide a detailed drawing of what your topology looks like.

Beast6 · ‎04-08-2019

Hi, @Georg Pauwen

Yes, Loopback6 is the same as the IP address used in static NAT entries.

I am attaching 2 diagrams here I think that might make senses how it is laid out.

Georg Pauwen · ‎04-08-2019

Hello,

did you apply the changes to the ZBF that I suggested, and if so, what if you remove all static NAT entries for the Loopback ?

--> no ip nat inside source static tcp 200.20.21.142 554 X.X.X.62 554 extendable
--> no ip nat inside source static tcp 200.20.21.142 9200 X.X.X.62 9200 extendable
--> no ip nat inside source static tcp 200.20.21.142 22609 X.X.X.62 22609 extendable
--> no ip nat inside source static udp 200.20.21.142 22609 X.X.X.62 22609 extendable
--> no ip nat inside source static tcp 200.20.21.142 37777 X.X.X.62 37777 extendable
--> no ip nat inside source static tcp 200.20.21.142 37778 X.X.X.62 37778 extendable
--> no ip nat inside source static udp 200.20.21.142 37778 X.X.X.62 37778 extendable

Beast6 · ‎04-08-2019

Hello, @Georg Pauwen

I didn't make any changes so far, I just need confirmation from you so that is the reason I posted the topology.

I am gonna make the changes you mentioned as soon as possible.

each static NAT has configured in such a way that it tells the remote site IP 200.20.21.142 to nat inside with a public IP X.X.X.62 and to open the particular ports for that customer.

Still, you want me to remove all static NAT entries for the loopback as mentioned?

Thanks.
