Hello everybody, and sorry for making you help me again
I have an ASA 5505 here (code to be furnish at the end)
Please note that the IP adress for the outside interface are exemple since this is a lab atm
This router is gonna go inside a small company.
This company use a SBS 2003 Server with exchange on it
So we need the route to do 3 things
1) Make the local lan access the internet : This is working as inteded
2) Make a VPN from the outside and access the lan : This is also working
3) We want to make people (after we change the DNS for it) to be able to do exemple mail.aaa.aaa and be able to access the Mail server from Outlook without beein on the internet and the OWA from the browser
Currently we only have 1 IP adress from the ISP, so i need to be able to access it from the same IP as the VPN (if possible)
I wanna know how to make it work as exemple just beein able to access port 25 from it
And how to make it accessible from multiple ports exemple 110 25 587 etc (all email ports)
my inside mail server is 192.168.0.2
How can i make this work
If you have any question don<t hesitate to ask i<ll do my best to answer

I made a mini mistake
we got 2 IP adress from our ISP, but I wanna kinda assign both to ETH0/0
So exemple 10.0.128.1 for VPN (works)
10.0.128.3 NAT to 192.168.0.2 for Email server (but only specified ports)

Thanks alot it worked, sorry for the late answer had lot of work
I have a 2nd problem if you can help me for the same setup kinda
The lan of the office is 192.168.0.0/24 (a bit dumb but sadly too many stuff to do to change it)
So i would like to be able to say exemple
On the VPN connection (IP adress from the pool 10.250.128.0) if i wanna RDP on exemple PC 192.168.0.200 instead in my RDP program i type 192.168.200.200 and the cisco will convert it to 192.168.0.200
I hope you can help me, (same config as the first post)
Sorry about all these questions but these config are a bit advance for my knowledge but still learning!
