Nat through DSL Modem-router to Cisco 2621
Posted on 2004-09-06
Ill try to keep it simple and short....
I have 5 static IP address's on my dsl subscription, 69.xxx.xxx.81 thru 69.xxx.xxx.85, the Modem/router is 69.XXX.xxx.86.
Net mask is 255.255.255.248
The int fa0/0 is(outside) 69.xxx.xxx.81 and int fa0/1 my internal network is 172.16.xxx.xxx/16.
I can ping thru the router to the outside, but I can not ping from the modem to the inside.... this is where my woes begin....
I want to be able to set up a web server, a ftp server and an RDP connection for people to hit the server from the outside on ip 69.xxx.xxx.85.
but for some reason unknown to me, I can not get the router (2621) to pass the trafic thru.
I have removed my in bound access-list for trouble shooting purposes, so please dont think Im a fool running wide open....
I have included my sh run and as you can see I would like anyone who hits the 69.xxx.xxx.85 address, depending on port #, to either start an RDP session or Hit the FTP server. I have yet to set the NAT up for the http....I figure Im failing at two, why go for three....
So if you see the mistake that im not, please let me know...
thanks in advance people
