Hareware firewalls for dialup connections, do they exist?

Any router used in your home/office network also acts as a firewall; these
have the RJ-45 jacks.
In order to avoid adding more software overhead to my already slow computer,
I
was wondering if a hardware firewall exists for computers using ordinary
dialup that have RS-32
type phone jacks?
 
That's RS-232.

I have in the past setup the Asante FR3004C/DS a Cable/DSL and RS-232 port Router with a
FireWall but I think it was discontinued. It was basically a Cable/DSL Router that had a
RS-232 port for v.90/v.92 external modems as a fallback if the Broadband connection failed.
However, it worked just fine to share the Dial-Up modem connection.

However, the SMC Barricade SMC7004ABR may be substitute for the Asante and even includes a
print-server. I just haven't installed any of them as few people ask for a RS-232 fallback
capabilities anymore.

Yes, some D-Link routers are dial-up ready and I think use RS-232.

RJ-11 phone jacks or RS-232 serial I/O??

there's things like Actiontec's modem/router which i believe can handle
up to 255 computers, probably has DHCP built-in. it's only $60. yes,
the actiontec is not a firewall, but it does have NAT. there are some
routers which have serial ports and you can plug a modem right in (don't
ask me which brands).

if you can spare the space and electricity, just build your own
router/firewall/modem contraption out of an old PC. use Smoothwall,
IPCop, OpenBSD, Windows, whatever. certainly that will give you all the
features you want. about the only downside is the electricity costs,
but eliminating the hard drive should amerliorate this. there are at
least 30 distros/unices that are ready-made for this application.

Duane, what model ?

I could not find one made by DLink
http://www.dlink.com/products/category.asp?cid=2&sec=0#cid_22

I could find a VPN w/FireWall that uses a RS-232 port [DFL-200 VPN
Firewall ] but I don't think this is what Gary is looking for.

I'll have to ask a guy at work which model is it that he was using to do
that with his home connection. I'll post it when I get the information.

The Dlink Di-704 was one, as I used to have it. You could hook your external
dial-up modem to the router's 9-pin serial port and it worked very well with
it, cooperating with the modem to automatically dial your ISP whenever a
Winsock app was run. I imagine it wouldn't be hard to find one still on eBay
or Amazon Marketplace.
 
Just like the Asante model I mentioned, the DI-704 has been discontinued and is no longer
supported.
However the SMC Barricade [SMC7004ABR] I mentioned is still a viable product.

Netgear makes one and it must cost a pretty penny. I am sure there are
others that make them one just has to look. I think NG as a wireless model
too.

I check on the d-link model and don't recall DI-704 as being the model the
guy at work was using.

Well there 'ya go. We have provided two current models that Gary can get.

Netgear FR283S -- http://www.netgear.com/products/details/FR328S.php
SMC Barricade SMC7004ABR --
http://www.smc.com/index.cfm?event=viewProduct&localeCode=EN_USA&cid=1&scid=&pid=858

I would think the Netgear is the better choice, unless Gary wants a print-server as well..

While the 704 is long discontinued, the 704P and 704UP, with
parallel (P) or USB (UP) printer ports is still a current model.

My old ("revision A") DI-704P had the built-in serial port.
It had a brown or gray case. The current models of the DI-704P,
now in a silver case as seen at www.dlink.com/products/?pid=63,
do not have the serial port.

I have one of the SMC Barricade routers, SMC7004ABR. It has a serial
port for connecting an external modem as well as the standard ethernet
port for WAN and it has four ethernet ports for your local network,
LAN. I think one of the SMC wireless models also has a serial port,
but I am not 100% sure.

It works just fine and does provide the "hardware firewall". I had a
lot of problems getting it to work with the external modem. I
currently use a "bootleg" firmware version that one of the SMC techs
sent me via E-Mail.

Good luck, jimbo
 
I have DLink 704P routers here....the only ports I see are four LAN
and one WAN with an RS232 Printer Port, as this router can be used to
attach a parallel printer to.

Mine may be a newer/older model but there is not a 9 pin serial port.
I cannot order DI704 (without the 'P' any longer and this may have
been the one with the serial port).

The DI-604 was.is just about the same, but without the printer port,
I have them here too, but nada on the serial port.

The older 704P's had the serial port, the current ones do not.
