Piggybacking a network onto mine

Company next door have lost their internet bigtime. Was wondering if they could piggy-back onto one of our ASDL connection til they get theirs up and running. I cant give them the ADSL connection completely as I still need it for mail/web/vpn, etc.

They have a standard 4 port ADSL modem/router which assigns their IPs by DHCP. This is connected to their switch.

I have 2 ADSL accounts - one comes from a standard 4 port ADSL modem/router and the other is an FVX538 (8 port firewall router) connected to a Linksys ADSL2 modem. Both these are connected to my switch.

I presume that a standard cat5 cable from either my routerss into a spare port of their ADSL router will not work. Is there a way to do this?

Cheers,

Cat 5 from Your router to their switch and disconnect their router from their switch.

That would do it, but keep in mind it also puts them right on your network. There would need to be a decent amount of trust in place.

A very decent amount of trust.

Depending on the type of equipment you're using, there should be some ability to segment this off thru ACL's, VLAN's, and other variables.

Do your homework on this one.

Sorry, should've marked this as resolved, although not in the manner I wanted. I ended up giving them wireless access as they had a number of wireless enabled laptops. They do not have access to any other resource on my network apart from internet access.

That would do it, but not in keeping with their IP structure, but then again, I probably didn't explain it properly (mixture of fixed and DHCP ips on a different subnet to mine). But thanks for the helpful input.

Thats a bit harsh mate; I was only looking for a quick resolution to the matter in hand. I was just asking to see if someone had a quick resolution without having to rework their/mine system.

That would add complexity to the matter.

If they can live with wireless for the short time, that takes care of the situation.

Didn't anything at all derogatory by that comment. You just want to make sure you understand to the 'T' the solution you choose due to the ability to hose this and compromise yourself/network. More of a 'double-check your work' than anything demeaning.

Thanks for that Silicon Scream. I guess you could call it a case of 'crossed wires'.
