Cisco 1750

[Trixanno]

Has anybody ever dealt with this model router before. I'm looking for some help on setting up my Iburst through it....

The ports that I have are
Serial 0
FastEthernet 0
Dialer 0

I would like to set up the iBurst modem to connect through the dialer port, connecting the router through the ethernet port to a switch.

The idea is to have the router permanently connected to the iBurst modem, and then having the pc's on the switch connect through the swith to the internet. My goal in this exercise is to have a permanent live internet connection through the router.

Any assistance in this regard would be greatly appreciated

This is a hackup of a config posted here a while ago for a Cisco with 2 Ethernet interfaces. I modified it for one FastEthernet interface, however I dont have Cisco to verify it on, so some tweaking/fixing might be neccessary ...

The problem I sat with was the fact that there was no Ethernet 0 interface. But it looks as if you have fixed the issue in this configuration. I'll load it on and report back in a while.

Thanks for now.

Roman4604 Thanks for your help so far.
I Uploaded the config file, 2 issues however. MMI & PPPoE not recognised. according to me these are 2 fairly big issues. I checked my IOS, and it's Version 12.0(3r)T1. You don't by any chance know what version was used for the config you posted?

I also had to take out the 'adjust-' from "ip tcp adjust-mss 1312". This, I think, confirms that it's a version thing, I hope, It would be nice to actually start using my R7000+ piece of equipment.

 

[Roman4604]

IOS 12.0 is very old, I would recommend you find at least 12.3(x), but possibly a later 12.2 could do the trick. Looks like your 12.0 doesn't even support PPPoE yet, and the adjust-mss statement syntax was probably changed in later versions.

Also you're going to have to verify that a later IOS can be accomodated by your router's memory & flash ... as the versions go up so do their resource requirements.

Sorry cant be of more help.

Why do you want to use the Cisco router to manage your iBurst connection?

 

[Trixanno]

Why not?

The biggest perk I would like to get out of the relationship is "alway on" internet. The idea of getting disconected when on idle just freaks me out.

I wouldn't mind having a Cisco instead of my cheapy D-Link 624+.

From a features & flexibility point of view, there is nothing that can touch Cisco IOS. If you know how to configure, the amount of fancy stuff you can do is awesome e.g. traffic rate mgmt, complex NAT/PAT configs, multi link/technology load balancing & failover, policy routing of traffic over multilinks, adv. monitoring, firewalling & intrusion detection, adv VPN configurations & native VoIP to mention a few.

Just not worth it if you have to buy it yourself i.e. R800 vs. R8000+.

And the R8K is if u already know how to config it. If you dont and u get it, shell out even more to learn how to do it

Just bought a 871 Ethernet unit to do exactly this at around 4k, the 871's got better support for SIP management (faster processing) but the 851 can be had for half the price, come to think of it, any current 8 series these days can do PPPoE, Hmmm, ADSL port and IBurst with traffic management, that could be interesting...

I think PPPoE was first introduced in 12.3 for the 1750, also the last software release train for the device.

...so instead of paying R8k for a Cisco, would a R800 router + Smoothwall also be useful?

Besides, Smoothwall is free and open source...

Just my 0.02c...

Why a router too if you use Smoothwall / IPCop?

BTW, I see Roman4604's point about Cisco, but for mere mortals using iBurst?
IPCop / Smoothwall seems like a bargain, especially if you have old hardware lying around...

[Edit] "alway on" internet is available with IPCop and Smoothwall, I've seen up to 10 days with no disconnection, power failures (and old UPS batteries) being the main cause of disconnects.

Cisco is a proven name in this industry and it's nice to be able to support them.

Now I just need to do a CCNA to have a deep understanding of all the functions I can get out of their name.

I tried looking around for a new IOS, but can't seem to find anything. Except for on cisco's website, but you need to be a registered user for that access. Does anybody know where I can get the latest version of their operating system?

One last thing, I mentioned earlier that MMI is also an unrecognised syntax. Is it similar to PPPoE, and was only incorporated into the IOS in the versions after the product launch?

 

[Trixanno]

Ok...this should be my last question...anybody know where I could get my fingers on a cool GUI for Cisco routers. Not only one that gives you stats, but one for configurations etc?

Sorry, cool GUI's only start on later versions of IOS and newer routers...

Security, VPNs, QoS (quality of service) depends on the type of router and IOS. good broadband routers will be the 800series router, its comes with a serial, fasthethernet, rj-11 jack(will be used for you adsl connecton)
