i assigned my server internal ip address: 172.30.6.5
in netscreen 5xt, i added Trust external address 66.253.99.135
i created a new policy from trust to untrust > source address is 172.30.6.5 and destination address is 66.253.99.135. under service, i allowed multiple such as http and other.

when i try to access 66.253.99.135, it should take me to my server externally but it does not work at all.

Please help.

i got it figured out. netscreen untrust interface is 66.253.99.130 > here i added MIP 66.253.99.135 mapped to 172.30.6.5.

my current problem is Ping. i can't ping 66.253.99.135 either from inside or outside.

Ok, so in your policy do you have this MIP enabled for echo requests ? You should bind this MIP to a policy and as well you should allow the services you want along with ICMP (untrust to trust)

Yes, that should be good. So you are still not able to ping from external ?

Can you post your get config output here ?

Cheers,

Hello,

Did you try to ping your server from the inside(trust) using the translated Ip addresse? if yes this is normal have a look here

http://www.experts-exchange.com/Security/Firewalls/Q_22024323.html
http://www.experts-exchange.com/Networking/Q_22021398.html

else if you cannot ping your server from the outside and you have permit  ICMP this is a problem, so could you post your config and draw the network.

ping is fine now. it takes a few minutes but finally it works.

i now have another problem. i tried to add another MIP just like i did previously: netscreen untrust interface is 66.253.99.130 > here i added MIP 66.253.99.136 mapped to 172.30.6.6.

i won't be able too because it keeps giving me this alert messege: "The netmask is invalid"
it doesn't matter what i do, i changed different ip addresses for both but still got the same alert message without going any further.

any idea?

When creating the MAP for single IP you have to use 255.255.255.255 mask!!
