Router setup

[markd85]

Hi All,

I need some advice please. My current setup is two broadband lines attached to a pair of drayteks with static IP's. Here are the forwarded ports currently setup on each router.

Ports forwarded line A
Webmail - 80 - 192.168.6.65
Webmail S - 443 - 192.168.6.65
SMTP - 25 - 192.168.6.65
VPN - 1723 - 192.168.6.45

Ports forwarded line B
Intranet - 80 - 192.168.6.30
Sharepoint - 443 - 192.168.6.30

We are currently thinking of changing ISP's and using a bonded broadband service. I beleive the bonded setup we will only get 1 static IP, and port forwarding will have an issue as I have both 80 and 443 forwarded on one static IP. The router we are thinking of changing to is a Cisco 1841, can anyone suggest a way that this can be acheived. Can i forward depending on the http header for example...

http://intra.xxxx

http://mail.xxxx

I hope this makes sense, any help would be appreciated.

Thanks

Mark

why can't you get a /29 from the service provider??

Hi thanks for your reply, /29 ?? Not sure what you mean sorry. Can you explain.

Thanks

Are you meaning we could get say two static IP's for the one service and have the second IP as an alias?

a /29 is a CIDR prefix that gives you six usable ip addresses (five actually since the service provider gateway will take one) to use for external resources. all you need to do is ask your service provider for a /29 and they'll know what you mean. your alternative is to map the duplicate external resources to different ports (i.e. port 80 and port 8080 for http and 443 4343 for https)

Thats great thanks for the info.

Do you have any experience of bonding ADSL? We are considering going with Timico, but i've had mixed responses from BT business who tried to put me off.
