Frame-Relay Problems/ NAT

jack84ie · February 2011

Hi, trying to get his Network Working, but Frame-Relay just does not want to Work...

It is in Packet Tracer in Cloud0
Serial0 set DLCI 201 R4 - R6 DLCI 201 R4 - R5
Serial1 set DLCI 103 R5 - R4
Serial 2 set DLCI 201 R6 - R4

then into Frame-relay connections
From Port Sublink To port Sublink
Serial0 R4-R5 Serial1 R5-R4
Serial0 R4-R6 Serial2 R6-R4

done Ip map on R1

but if i do an ip map on R5 or R6 it stats ip address already map
R4 shows Frame-relay shows both map address
R5 shows Frame-relay map address Down
R6 shows no Frame-relay map address

With NAT i have a public IP of 195.100.190.0/24 R1 can ping Loopback 0 on ISP Router

but trying to do a ip route 192.199.190.0 255.255.255.0 S0/0/0
it comes up invaide interface type and number..
evening if i do a 192.199.190.240 255.255.255.240

I am Trying to get ISP to ping the Public Address and have R1 translate between Public and private

are you able to post the PT file? Will be much faster to work on it.

what are you Natting? outside in or inside out? or both?

what type of NAT? one to one, one to many?

how does the outside address get an inside address?

how does the inside address get an outside address?

hint: you are missing some CLI statements that NAT the outside address
to an inside address and vice versa

side note: another question to ask: can you NAT multiple [WAN] subinterfaces to a single [LAN] subinterface?
if so, how does the router know to do that?
