Make DSL look like dial-up

My ISP insists on a dial-up connection to connect to SMTP and POP servers. Is there any way I can make a connection via DSL "look" as though it has come from a modem?
 
tbalazs,

How is it the ISP is insisting on a dial-up connection? Are they looking at the subnet? or something else?

I have no idea how it's being done: in fact the ISP might be being a bit sneaky and not telling the truth. ISDN works OK, just DSL doesn't. Maybe it's a subnet or IP range thing...
 
What happens when you set your mail client with the POP3 and SMTP server addresses? Do you get an error message?

What mail client are you using?

Do you mind saying who your ISP is?
 
No you cannot get your dsl to act as a dialup. Its possible your ISP may have some sort of private network which they NAT at some point to access the Internet. This means that chances are you will not be able to get to the mail server because it may have a private IP address.

Try this....

Connect to your ISP with your dialup modem. Then check your ip configs for the PPP adaptor. What IP address did you get assigned? If it is 10.x.x.x or 192.168.x.x then they definitely have a private network. Otherwise find out what the IP address of the mail server is and try to ping it out your dsl connection. If you can ping it there shouldn't be any reason why you can't simply configure your mail setting to point to the appropriate server.
 
Sounds like a dodgey ISP to me. I can't imagine what reason they would have for only allowing dial up access to their POP3 and SMTP servers but they can enforce it using access lists or firewall rules. If your DSL service is on dynamic IP then it will be a different range to that of the dial-up users. They could only be allowing access to the IP range of the dial up users, but I can't imagine why they would do that.

Could you post the ISP's name and we'll check.

Chris.

tbalazs,

What they are probably insisting on is using their "network". I used to use RCN for dialup. When I got DSL some time back, it was through Verizon. Initially, I was able to get into my RCN mail with no problem. After a time, I was unable to access their servers and found out they had instituted a new policy requiring that you be on their network to access the servers. As far as I know, they are looking at the IP and subnet to verify this. If your DSL is through the same ISP, this should NOT be a problem.

While I think it is nit-picking, I can still understand the reasoning from an ISP's perspective. They don't want just anyone using their servers, especially these days with spammers, theft-of-service and virus threats. Verizon requires that the sender of an email be a valid Verizon account, so if I wanted to send an email under some personal address, it would be bounced. Many consider this to be restrictive also.

Bottom line is, it's their facility and they can protect it whatever way they feel is right. There are plenty of ISP's out there and if this one's policies seem wrong, you can always switch.

Hope that helps.

Sounds like a REAL dodgy ISP if it's assigning you an IP from a private range -- as in, don't expect to be able to play games online or do anything but e-mail and surf. More than likely they couldn't get assigned a block of IP addresses and are trying to cheap their way along.
