unable to reach peer end public IP via vpn tunnel

L3 Networker

HI Team


I have created S2S VPN tunnel between palo alto and cyberoam firewall.


Tunnel is up but the traffic is not flow.


Under Cyberoam firewall there is one server with public IP 144.21.X.X.

From palo alto we need to reach the peer end public IP 144.21.X.X via the vpn tunnel.

but whenever I tried to reach the peer end  public IP 144.21.X.X its going via the internet rule instead of vpn rule.


Our requirement is that traffic should go via the vpn tunnel to reach the IP 144.21.X.X


I have configured the PBF policy but its not work.. Please help on this

This is expected.

Your PEER IP communication will happen over internet only. The proxy IDs configured will only pass through tunnel.

Hi @MohammedAsik Check if routes are pointed towards proper tunnel interface. 


Verify traffic logs once if matching correct security policy and sending traffic to correct tunnel interface.




Please find the below routing and security policy details   10   A S   tunnel.10


from inside;
source-region none;
to vpn;
destination-region none;
user any;
category any;
application/service 0:any/any/any/any;
action allow;
icmp-unreachable: no
terminal yes;

Hi @MohammedAsik What is in the route? is it next hop?


What you found in traffic logs?? Is firewall passing it to same tunnel interface?






its a tunnel interface. thats why its showing next hop as


In traffic logs its taking the internet rule and its not pass through tunnel interface. its passing through internet interface Ethernet 1/1.

Can you please check once if tunnel interface belongs to VPN zone?




Please find the below ss  tunnel.10 interface 




Something is mis configured .  Check any pbf which is sending traffic on external interface or traffic getting NAT?

please share traffic log snap?
