Hi,

I have an exchange server that I am trying to access through a pix vpn.

Do I need to setup access lists for both firewalls?  And if so what is the most secure way?

example

exchange server 192.168.1.x/10.1.x.x
pix 506e<---vpn-->
exchange client 192.168.2.x/10.2.x.x

Any help would be greatly appreciated.

Both firewalls ? I see only a single firewall here.

It would be a good start to set the ip address (internal ip) of the exchange server in the 'hosts' file of vpn client so that the resolution happens fast.

2 main things that you might encounter with exchange and outlook over vpn is 'name resolution' and 'mtu problems'. So do the first thing and see if it gives a better result.

If this is not what you meant, then please explain and also post the config.

Cheers,
Rajesh

thanks

I had already added the ip address of the exchange server.  I am also able to ping the server.  

I am separated by two pix 506e firewalls.  The vpn is established.

example:

my pc-->pix 506e-->dsl-->internet<--dsl<--pix 506e<--exchange server

Oh Okay, that would be enough on the security aspect as long as you access the exchange server through the VPN.

The VPN should be configured already with security with access-lists and so no problems. If you think there is something of concern, post the config and lets see.

Cheers,
Rajesh

You were correct about the 'hosts' file.  I had logged in on an xp machine with a different account.

thanks
