Hi All,

I hope you can help, as i have been trying to get this to work for the last couple of days.

We had a netscreen in our office to support are remote site, we had a 5GT with policy based vpn tunnels to the remote site which also run 5GT. We have more then 10 sites to support, So i got a second hand ns204 and erased to factory settings and uprgared firmware to 5.4.

I can get the tunnel to come up and can see the SA status is active under the monitor status on both netscreen. But i cant seem to pass any traffic via the VPN tunnel. IF enable logging on the ploicy on both netscreen. I can see the traffic going out on the ns204, But no data in the logs on the 5gt on the remote site.

I have tried most things and have got ns204 talking to other netscreen 5gt fine!

Hope some one can help

Thanks

Hello,

I would enable debugging on each end of the tunnel and check the db stream. I would also try and use a few flow filters.

On 204:
set ff dst-ip x.x.x.x ip-proto 1
set ff dst-ip y.y.y.y ip-proto 50

On 5GT:
set ff src-ip y.y.y.y ip-proto 50
set ff src-ip z.z.z.z ip-proto 1
set ff dst-ip x.x.x.x ip-proto 1

NOTE:
x.x.x.x = trust ip on 5gt
y.y.y.y = 5gt untrust ip
z.z.z.z = trust ip on 204

debug flow basic <-- on both NS's
clear db <-- on both NS's

From 204:
ping x.x.x.x from (trust interface)

get db str <-- on both NS's

undebug all
clear db

If you like, feel free to paste the results of "get db str" to this site.

Hi Thansks for your reply, sorry i have not posted before!

Here is the ouput

i have changed the real ip address to

ns204IP is the untrusted interface of the 204
NS204GatewayIP is router IP.
NS5GTIP is the 5GT is the untrusted interface 204

Hi,

OK, it appears your traffic is being route, permitted and encrypted on this end OK. Do you have the debug output from the remote Netscreen? Please post it.

Hi,

This doesn't really help. Did you apply flow filters at the remote site? We need to see the inbound IPSec packets. So I would apply a filter on the remote firewall that logs ip protocol 50 using the public source IP of the local FW. Keep me posted.

Rgds,

John

Hi,

It looks like the remote firewall is dropping the inbound IPSEC traffic. Can you try to debug IKE on the remote firewall? Also, please enter the "get sa" command and post the output.

debug ike all
clear db
<ping from the local site)
get db str

Rgds,

John
