My setup is as follows:

NT4.0 workstations from 192.168.1.xx range, gateway is 192.168.1.1
Point to point T1 using Cisco2514 with 155.145.45.34 serial on other end and 155.145.45.35 Serial0 on my end which will be using NAT. How will I configure my router so 155.145.45.35 is the only IP seen from the other end? What will be my Ethernet0 settings be? I do not have any idea of how to go about configuring this.
 
u can setup a static NAT rule that overloads your 192.168.1.0/24 class onto your serial interface IP address...

u will need to create an access list that has got your internal workstation IPs.. then include this list in your NAt statement.. all these IPs will be loaded from the list and NAT'ed to the serial interface IP address... below is s config...

access-list 7 permit 192.168.1.x
access-list 7 permit 192.168.1.x
!
ip nat inside source list 7 interface serial 0 overload
!

good luck...
 
You should also configure your interfaces to enable NAT translation.

e0 ip nat inside
s0 ip nat outside
 
Should my LAN gateway be my e0 ip? How do i take out a line from the configuration? i have this now:
e.g.

ip nat pool ovrld 155.145.45.35 155.145.45.35 prefix-length 24
ip nat inside source list 7 interface Serial0 overload
!
!
access-list 7 permit 192.168.1.xx
access-list 7 permit 192.168.1.xx
access-list 7 permit 192.168.1.0 0.0.0.50 (this was here before, should i take it out)

i do have e0 ip nat inside and s0 ip nat outside.
thanks for the initial help, please bear with my ignorance on this things.
