[zebra 23115] BGP routes can't publish!

I'm in need of help as soon as possible.

 

Here's the scenario:

 

I'm using BPG as just a route publisher traffic doesn't actually filter
through my Zebra box.

I have Time Warner as my ISP AS4323.  From the timewarner router traffic
flows into my Cisco 515Pix firewall.

My Zebra box is behind my firewall in my DMZ. I have a NAT'd IP & port
179 port open for the Zebra box to allow routes to publish.

 

I've gotten the bgp session established with timewarner but I'm unable
to get routes sent to them.

I'm not sure if I should be using multihop or if the problem is much
deeper. So far I have not been able to get a next hop defined.

As you can see towards the bottom the next hop route is missing how can
I get this working to publish routes?

 

 

 

Here are the details:

 

ZebraConf:

 

log file /usr/local/etc/zebra.log

!

interface lo

!

interface eth0

 ip address 192.168.173.105/24

 multicast

 ipv6 nd suppress-ra

!

ip route 0.0.0.0/0 192.168.173.3

!

line vty

end

 

 

BGPConfig:

 

Current configuration:

!

hostname Frodo-bgp

log file /usr/local/etc/bgp.log

!
