Hi
I'd like to setup an 1800 router as a firewall, but with two internet feeds setup to share the load over both. I'm told that just configuring two default routes will cause the router to do per connection load balancing of outbound connections...is this correct? How would I handle inbound connections, ie. Mail, FTP, etc? Would I just configure the DNS record (ie. the mx record) to point to both public addresses? Thanks very much.

Hi Jason,
Yes, you can use DNS load balancing (round-robin only). i.e.
ftp.domain.com. 180 IN A ISP-A_IP_Address_Provided
ftp.domain.com. 180 IN A ISP-B_IP_Address_Provided

Hi,
well if you have 2 routers could go for GLBP instead of using static floating routes as default g/w on a single router..... itll give u redundancy for the routers too..
hope it helps..

We only have the one 1800 right now and the client is on a tight budget. The reason for the need of load sharing is that the client is waayy out in the middle of nowhere and any one single internet feed they can get out there is much too slow (1Mb at best). Thanks

HI Jason, [Pls Rate if Helps]
2' Concepts of Load Balancing:
1. Per Packet Load Balancing
==>Allows the router to distribute the packets based on Destination address. Normally, Packets are guaranteed to take the same PATH
==>Enabled by default in Router and is most preferred concept.
2. Per Destination Load Banalcing
==>Allows the router to distribute packets regardless of HOST / user sessions. It uses Round Robin method ie., 1st Packet over Link-1 and second Packet over Link-2

Hi
Thanks for the quick response. I had seen that document and it explains how the outbound traffic would work quite well, but I'm kinda foggy on how inbound connections would work. Would I just create two A records for the same domain name, each one pointing to one of the public addresses? Thanks

HI,
A single record can be mapped to any number of Public IP Address.
Pls check with your Service Provider for this requirement.
