ASAv5 <> Zywall 310 VPN not passing traffic & policy routing

swilmerism
Level 1
Level 1

Afternoon,

Im after help on a VPN between 2 devices.

 

Cisco ASAv5

Cisco Adaptive Security Appliance Software Version 9.8(1)
Firepower Extensible Operating System Version 2.2(1.47)
Device Manager Version 7.8(1)

 

Zyxel Zywall  310 4.30(AAAB.0)

 

The Zywall is the core router with VPN's out to other sites (other zywall routers) with poilcy routing workign fine. - I can set these up all day long no probs..

Ive setup this new VPN to cisco ASAv . Currently the VPN is up but not passing traffic.

VPN made using the Site-to-Site VPN Wizard in the ASDM. ALl good. but a trace route out from the ASA ges out of the WAN Id expect it to go down some VPN interface but cannot see one. >

      remote ident (addr/mask/prot/port): (172.16.100.0/255.255.252.0/0/0)
      current_peer: xx.xx.xx.xx

 

 

Any pointers please?

The wizard is creating a policy based VPN, so no VPN tunnel interface will be created.

Also a traceroute initiated form the ASA will not be sent over the VPN tunnel.

For testing the VPN tunnel on ASA you can use packet-tracer. It will not actually send a packet through the tunnel, but it should bring it up and you should be able to see that the packet would be encrypted.

Otherwise you will need a device sitting behind the ASA to test.

I am doing my test pings from the LAN interfaces of each device so was expecting pings to go through tunnel.

Thanks for the packet-tracer suggestion, ive done it and results below.

Still struggling...

It looks like you have a ACL rule on the inside acl that is denying traffic from 192.168.202.2 to any.

Hi,

thanks for the advice,

 

still struggling. I see its "implicit rule" thats stopping this.

Yet i have added many permit's the only deny is the implicit rule. Ive even added ACL for the hosts im testing too & from

I have followed this and made changes but still having issue > https://www.petenetlive.com/KB/Article/0001108

Packet traces in both directions attatched.

 

 

HAve now factory defaulted the ASA

I only gave it a inside + outside ip addresses then ran the VPN wizzard

Same again

VPN is up ok but not passing pings.

 

heres my config >>
