Struggeling with Self Zone Security

i,

 

my Hardware:
C1131X-8PLTEPWE
IOS Version 17.15.3a

I’m currently trying to map my classic ACLs into ZBF.
That has worked fine so far, but I don’t understand the Self-Zone logic.

 

Even if I activate the zone member to my wan interface:

interface GigabitEthernet0/0/0
zone-member security OUTSIDE

As soon as I try to do this – even with inbound and outbound permit ip any any – I can no longer ping or SSH from the remote location,
for example from IP 10.1.9.5.

 

Without these commands, and acitvated interface GigabitEthernet0/0/0 zone-member security OUTSIDE it works...

zone-pair security ZP_OUTSIDE_TO_SELF source OUTSIDE destination self
 service-policy type inspect PM_SELF_IN

zone-pair security ZP_SELF_TO_OUTSIDE source self destination OUTSIDE
 service-policy type inspect PM_SELF_OUT

 

 

 

Here’s a snippet of my config:

 

ip access-list extended ACL_SELF_IN
 permit udp any object-group OG_WAN-IP eq 500       
 permit udp any object-group OG_WAN-IP eq 4500     
 permit esp any object-group OG_WAN-IP              
 permit tcp any any eq 22
 permit icmp any any 


ip access-list extended ACL_SELF_OUT
 permit tcp any any eq 443
 permit udp any any eq 53
 permit tcp any any eq 53
 permit udp any any eq 123
 permit icmp any any 
 permit tcp any eq 22 any
  permit esp any any
 permit udp any eq 500 any
 permit udp any eq 4500 any

class-map type inspect match-all CM_SELF_IN
 match access-group name ACL_SELF_IN

class-map type inspect match-all CM_SELF_OUT
 match access-group name ACL_SELF_OUT

policy-map type inspect PM_SELF_IN
 class type inspect CM_SELF_IN
  pass
 class class-default
  drop 

policy-map type inspect PM_SELF_OUT
 class type inspect CM_SELF_OUT
  inspect
 class class-default
  drop 

zone-pair security ZP_OUTSIDE_TO_SELF source OUTSIDE destination self
 service-policy type inspect PM_SELF_IN

zone-pair security ZP_SELF_TO_OUTSIDE source self destination OUTSIDE
 service-policy type inspect PM_SELF_OUT

interface GigabitEthernet0/0/0
ip address 195.xxx.xxx.xxx 255.255.255.248
 ip nat outside
 zone-member security OUTSIDE

have to pass ssh and icmp instead of inspect on both sides.

Thats worked for me now.
And the Match-All also works !!!

Cant do this, because its a remote location and if i try to create the self zone pair, i'm not connected anymore with ssh session.

I just said that I can't apply this configuration because it would kick me out of my remote session.
That's why it's not there.

@florian.hanig1 your VPN ACL encrypts traffic from source 10.8.0.0/16 to any, so for traffic to be encrypted over the tunnel the traffic must come from GigabitEthernet0/0/1.90? that interface is a member of zone Z_VLAN50.

Do you have a zone pair for Z_VLAN50 to OUTSIDE and vice versa?

GigabitEthernet0/0/1.90 is a member of zone "Z_VLAN90" not 50...

Zone pair for Z_VLAN90 to OUSIDE is:

zone-pair security ZP_V90_OUT source Z_VLAN90 destination OUTSIDE
 service-policy type inspect PM_V90_OUT

policy-map type inspect PM_V90_OUT
 class type inspect CM_V90_OUT
  pass
 class class-default
  drop

class-map type inspect match-all CM_V90_OUT
 match access-group name ACL_V90_OUT

ip access-list extended ACL_V90_OUT
 10 permit ip 10.8.9.0 0.0.0.255 10.0.0.0 0.255.255.255

 

and other side...

zone-pair security ZP_OUT_TO_V90 source OUTSIDE destination Z_VLAN90
 service-policy type inspect PM_OUTSIDE_IN

ip access-list extended ACL_V90_IN
 10 permit ip 10.0.9.0 0.255.0.255 10.8.9.0 0.0.0.255

class-map type inspect match-all CM_V90_IN
 match access-group name ACL_V90_IN

 class type inspect CM_V90_IN
  pass
 class class-default
  drop

policy-map type inspect PM_OUTSIDE_IN
 class type inspect CM_V10_IN
  pass
 class type inspect CM_V20_IN
  pass
 class type inspect CM_V30_IN
  pass
 class type inspect CM_V40_IN
  pass
 class type inspect CM_V50_BLOCK_RFC1918_IN
  drop
 class type inspect CM_V60_IN
  pass
 class type inspect CM_V70_IN
  pass
 class type inspect CM_V90_IN

@florian.hanig1 do you have a policy from outside to Z_VLAN90 to allow the return traffic as you are only passing (rather than inspect) the traffic?

@florian.hanig1 do you have NAT exemption to ensure traffic is not unintentially translated and thus not matching the correct ZBFW rule?

ip nat inside source route-map nonat_coco interface GigabitEthernet0/0/0 overload

route-map nonat_coco permit 10
 match ip address coco_nat
 match interface GigabitEthernet0/0/0

ip access-list extended coco_nat
 10 deny ip 10.0.0.0 0.255.255.255 10.0.0.0 0.255.255.255
 30 permit ip host 10.8.1.100 any

 

I would like to emphasize again that it works without restricting the Self Zone.

You config is correct there is no issue at all

You allow icmp any any and action pass for both directions 

Now only thing that make me suspect this config not work is use object network' please use subnet instead of it.
