Cisco 675 & SMC Barricade FTP question

[Bronko]

I have USWest DSL service, which uses the Cisco 675 external DSL router. I love it, and am only 500' away from the CO. After having nothing but problems with printer sharing, I purchased an SMC Barricade broadband router which also has a parallel port. It works great. So I have:


Phone Line <-> Cisco 675 <-> SMC Barricade <-> 4 computers

The local machines receive 192.168.X.X IP addresses from the SMC, before I would receive 10.0.0.X addresses from the Cisco. No problem, everything still working great. Lately, I have had a need to transfer files from work to home, and would like to use FTP to do so. I know how to open the port on the 675, but am wondering if the SMC will get in the way. Will I need to configure anything on the SMC as well? Any suggestions or help is greatly appreciated, thank you.


PS: I know having the SMC behind the 675 is redundant, but the print server was worth the price alone (108.00).

TTT. Any help is appreciated!

See my post to Absinthe. We have about the same set-up except I have a &quot;regular&quot; Ethernet Hub
vs. your SMC Broadband.

I'm currently using the Cisco but don't have the SMC router. But I would think that you need to disable NAT on the Cisco or SMC router. It would be a nightmare to have to configure both.

You WANT to have NAT Enabled on the Cisco 675 ( and DHCP ).

Here's my set up on a 5 node home LAN and it works flawlessly:

--DHCP and NAT Enabled on Cisco 675
--Cable from wall jack to WALL connector ( RJ-11 ADSL ) of Cisco 675.
--UTP Cat 5 from ENET connector of 675 to any port on Linksys 10/100 5 Port Fast Ethernet Hub.
--UTP Cat 5 cable from Hub to NIC ( Linksys 10/100 ) of each node.
--Each NIC configured as follows ( Control Panel/Network/Properties ):
-Obtain IP Adress Automatically
-Use DHCP for WINS Resolution
-Gateway...(leave blank)
-Enable DNS
Host: Qwest
Domain: Qwest.net
DNS Server Search Order
204.147.80.1
204.147.80.5

Tharsis, if my setup was like yours, I probably would not have a problem. But I have the SMC Barricade between my LAN and WAN connection. My problem is how to enable access through the Cisco 675 and the Barricade. I telnetted into the Cisco and opened up the port for my FTP hosts IP address. I know it is working, I can FTP from another machine on the LAN. The problem (I think) is that the SMC Barricade is blocking incoming FTP access (from the WAN) to the FTP Server.

Anyway, thanks for the assistance.

Don't know what else to suggest other than consider a Linksys Fast Ethernet 10/100 5 or 8 Port Hub. The 5 porter rig is about $69 at Best Buy (+ or - ). Maybe sell the SMC to a friend?
The configuration I outlined WILL work and give you DSL sharing ( and file and printer sharing on
yr LAN..assuming it is config'd OK ). I thought it would be a big deal to get DSL sharing on my MegaBit/Cisco 675, but it was really a snap....let me know if you have any more questions...

Tharsis: Are you able to FTP in to one of your machines on the LAN, from outside?

 

[Tharsis]

Bronk:
Yes..FTP download from any machine on the LAN works fine...

Bronk:
Is your Cisco 675 configured for PPP? I live in the Twin Cities and all MegaBit/ Cisco 675
users were required to convert from Bridging to PPP on Oct,1. The conversion is pretty straightforward, either using a &quot;wizard&quot; downloadable from Qwest or via HyperTerminal
using CBOS. The Hyperterminal method I prefer. As part of the conversion process to PPP
the options to enable DHCP and NAT are given. You want these enabled. After I configured my 675 to PPP, I downloaded and installed CBOS 2.2.1 on the 675 and installed Cisco Commander on each of the nodes on my LAN. Cisco Commander is a neat little utility that shows DSL connection statistics e.g bytes/packets TX,d and RX'd..CRC's..Connect speed, etc. You can get it from Qwest Web site also

Thanks for the help, but I still don't think we are on the same page. My goal is to be able to FTP into one of my machines from work. Not FTP from one of my machines on the LAN to the internet. I have the Cisco setup to allow this, but the SMC Barricade is in the way now.

 

[Tharsis]

Hmmm
Don't know about that. Good luck!

That's why you need to disable NAT on the SMC router. Other than that I don't see why it won't work. And Tharsis how often does your IP change. Mind change so often that people's downloading from my FTP is going crazy.

 

[Tharsis]

paldo:
Good question..I'm not really sure? Were do you check yours?

 

[pdo]

Just telnet into the Cisco and run the command show nat. Or you can just do it from Cisco Commander. But ever since I've upgraded my firmware to 2.3 something Cisco commander won't detect my router. So I guess Cisco Commander doesn't support firware higher than 2.2

 

[Bronko]

Thanks, I will look into disabling NAT on the SMC. I too am unable to use the Cisco Commander software, it does not detect the Cisco. Telnetting in and using Show Nat like you suggested will show your external IP address.

 

[Tharsis]

OK...I used the Cisco Commander >Show NAT< command and got my &quot;Inside Global Address&quot; number.
I'll check it periodically over the next 24 hrs and see if it changes...

[Tharsis]

New IP address as of 8:00am...so it changed in 14 hrs...

 

[pdo]

That sucks. Cuz mind use to change like every six months. Now that they are doing that I have a hard keeping my FTP server up

 

[Tharsis]

Yea..that's no good :-(
For what it's worth, I hooked up a 5-port 10Mbps Linksys Ethernet Hub to my &quot;main&quot; 5-port
10/100Mbs Linksys Hub via a 3' patch cable. I have 5 nodes on my LAN ( don't ask me why! )
and need 7 ports to do the DSL sharing setup outlined in the previous thread.
Guess what? It works perfectly! No degradation in DSL sharing capability and local LAN ( with NetBEUI ) still works fine. Documentation for Linksys Hub states you can chain up to 3 Hubs together in this manner....at that rate, I can justify building more PC's for quite awhile!;-)
