FTP & 2 hour IP lease - problem
Netbanger SImon Apr-27-01 07:03 PM
I have a SurfBoard cable modem attached to a Barricade router and 2 pcs connected to the 4 port switch.


My Cable ISP, NTL, only leases the Dynamic IP for 2 hours at a time, and so it is renewed constantly on the 2nd hour. I get the same IP reassigned each time though I've noticed.

If connected to someone elses server via my FTP client (WS FTP pro) and retrieving a large file (200MB +) my FTP client is disconnected if the lease time expires and renews whilst WS FTP is retrieving the file. I phoned the NTL tech support and they are telling me it is my router that is causing the problem and so won't support me :/

Can anyone tell me whether the constant renewing of the IP lease time would cause this problem with an FTP client, as I cannot believe that it is the router. Personally, I think the bloke was an idiot trying to get out of dealing with the problem but what can I do!

The router is set up for Dynamic IP address,a nd works fine for everything else.

When you connect to or whatever Local IP is assigned to your Barricade, the Remaining Lease Time says what? Mine currently says 167:00:30, the 167 being hours. Larry

Every 2 hours it starts off at 01:59.59 again. I found it hard to believe at first, but have had it confirmed that it is a 2 hour lease time. I was also told that it should really be four hours, and they are going to get back to me on that, or so they said... when, I don't know. Could be weeks or never knowing NTL.

A 24 hour lease time would be acceptable, but this is just stupidity. It's not as if they are being inundated with new customers, so such a short lease time would be totally uncessary, well IMO.

A temporary work around would appear to be an FTP program that can resume when the network breaks and can transfer more than one thread at-a-time. I do not know if WS FTP Pro can do that. SmartFTP (http://www.smartftp.com/featurelist.html) can. Larry

Thanks a lot Larry, I'll go and check that out. If I get a result from NTL, I'll post it here, just to conclude the thread.
