i am trying to setup a lan to lan tunnel between a draytek 2820 and a juniper SSG520.
the tunnel initiates ok (phase 1 and 2 ok) but no traffic passes between either side.
the juniper side of tunnel is NAT'd but the draytek is not.
DrayTek syslog has a message:-
NAT-Traversal: Using draft-ietf-ipsec-nat-t-ike-02/03, no NAT detected.
Can anybody help with this?
Draytek is running firmware: 3.3.4_232201
Regards,
Chris.
