SRX240 won´t route.

‎10-12-2012 01:00 AM

Hi everybody!

 

I am really struggling to configure Juniper SRX240 with JunOS12.1 to route the traffic. I have whole class of public ip-addresses, which I need to route through the router. My parameters:

ISP ip: x.x.x.40/28

ISP gw: x.x.x.43/28

Public ip: y.y.y.0/24

Currently the router gw: y.y.y.6/24

 

Configuration:

}
vlans {
    vlan-trust {
        vlan-id 3;
        l3-interface vlan.0;
    }
}

 

From the configuration next-hop should be ok, I believe, but when I check it, with command "run show route terse", I get:

inet.0: 3 destinations, 3 routes (3 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

A Destination        P Prf   Metric 1   Metric 2  Next hop         AS path
* y.y.y.0/24      D   0                       >vlan.0
* y.y.y.6/32      L   0                        Local
* x.x.x.40/32    L   0                        Reject

 

"run show interfaces terse" gives:

Interface               Admin Link Proto    Local                 Remote
ge-0/0/0                up    down
ge-0/0/0.0              up    up inet     x.x.x.40/28

                                            10.0.0.6            --> 0/0
                                            128.0.0.1           --> 128.0.1.16
                                            128.0.0.6           --> 0/0
ge-0/0/1                up    up
ge-0/0/1.0              up    up   eth-switch
ge-0/0/2                up    down
ge-0/0/2.0              up    up inet
ge-0/0/3                up    down
ge-0/0/3.0              up    down eth-switch

 

My goal is, to get from interface ge-0/0/0 internet connection and ge-0/0/2 to route traffic to network.

 

I would really appreciate any help.

Hello,

In your config, the 0/0 nexthop is pointing to self:

 

interfaces {
    ge-0/0/0 {
        unit 0 {
            family inet {
                address x.x.x.40/28;
            }
        }
    }
}
routing-options {
    static {
        route 0.0.0.0/0 next-hop x.x.x.40;
    }
}

 Please change 0/0 nexthop to your ISP gw (x.x.x.43 according to Your post).

HTH
