    Hi All,

    I configured Dyn VPN and I can connect to my local resources but cannot access the resources on remote VPN site.

     

    I have two vpn sites : site A (172.16.4.0/24) and site B(10.36.4.0/24) both connected using route based policy .Clients ( gets IP from 192.168.239.0/24 pool)  can connect to  site A using Dyn VPN , however they cannot access vpn site B . Added both sites as protected resource for both site A and site B in dynamic vpn configuration . I have only two security zone in my juniper box (internal and internet).

    In flow logs, i can see these, but it look like i need to create a policy from Internet to Internet ???

    Hi, vodexguy

     

    Can you share a "show interfaces terse" command?

    External interface (ge-0/0/0) and st.x interfaces are part of same zone "Internet". Since the traffic is coming from ge-0/0/0 and going out via st0.7 (same zone), you have to create a intra-zone policy (Internet to Internet) to allow the traffic.
