It's been almost more than a week, but I seem to have no answer for this and can't really figure out how to solve this:

I am using Fedora/CentOS Linux and have a Juniper SRX210 gateway configured as a site-to-site IPsec VPN. When I try to connect my Linux box to the Juniper, Juniper always shows 0 tunnels up.

The goal is to have Site 4 (Fedora/CentOS) connect to Site 1:

Please find below my configuration for both ends:

1. Juniper configuration prepared by this tool: http://www.juniper.net/customers/support/configtools/vpnconfig.html

Generated Configuration (Route-based):

## Configure interface IP and route for tunnel traffic
set interfaces st0.0 family inet address 10.2.2.2/24
set routing-options static route 192.168.1.0/24 next-hop st0.0
set routing-options static route 192.168.3.0/24 next-hop st0.0
set routing-options static route 192.168.4.0/24 next-hop st0.0

## Configure security zones, assign interfaces to the zones & host-inbound services for each zone
set security zones security-zone vpn interfaces st0.0
#set security zones security-zone trust host-inbound-traffic system-services all
set security zones security-zone untrust host-inbound-traffic system-services ike

## Configure address book entries for each zone

## Configure IKE gateway with peer IP address, IKE policy and outgoing interface
set security ike gateway ike-gate-cfgr ike-policy ike-policy-cfgr
set security ike gateway ike-gate-cfgr address 98.0.0.2
set security ike gateway ike-gate-cfgr external-interface ge-0/0/0
