How to route specific traffic through VPN?

[sdi]

Hi, I have succesfully established a site to site IPSEC VPN between two sites:

How do I now route specific traffic through that tunnel?

Example 1: route all SMTP-OUT traffic at site1 (HQ) out through that tunnel to site2 (Branch)

Example2: route all IP traffic to IP 1.1.1.1 through that tunnel? I tried to create a static route / subnet 1.1.1.1/255.255.255.255/Interface tunnel.  But traffic doesnt get through.

What did you specify as a selector? One of these IPs?

Does the traffic bring the tunnel up?

Do you have policies for the traffic type on both VPN gateways in both directions? If yes, did you check counters on the firewall policy?
