ESX server behind Netscreen

[heyyunus]

Hi,

Has anyone installed ESX server 2.x behind Netscreen-25 firewall.

I am working on an ESX server which is behind Netscreen firewall over VPN. Our VPN link is up and proper but sometimes i simply cant connect to the ESX server, but i can connect to other Windows based servers on the same VPN.

Any ideas? I checked the logs and found nothing, dont know whether ESX is causing problem or Netscreen. I have allowed everything (traffic) on the VPN network

Thanks

Are you trying to ssh or MUI into ESX? How are you connecting to the Windows hosts?

To the windows host i am using Pcanywhere and to VMWare ESX first i am trying to connect via SSH and then through the management interface (http)

Make sure you have ports 23 and 902 opened up on your firewall.

In my netscreen I have opened all services by specifying ANY.
This setting is only for the VPN network.
People who are accessing on the other side of the VPN are saying there is some issue related to ARP queries and the connection drops (ssh & http) after some time.

Hi, heyyunus

We have the same setup for almos two years and everythings works great, its the anyway to post the Netscreen information without the IP address of course...

Make sure that you alowd https traffic...

It was something related to the ARP timer which was set to default of 20 mins. I changed the ARP time in the NS-25 to 5 hrs, After that it is proper.
