I have 3 sites. 1 main site and 2 branch office sites. main site is isa
2006.
remote sites are pix 501's. the 2 branh sites are vpn into isa 2006. how
do i
allow communication between branch offices?

Assuming you used a Site-to-Site VPN.
You would have created "names" for the Network Objects for each
branch,...such as for example Branch#1, Branch#2.

The Access Rule would follow this pattern:
Source: Branch#1, Branch#2
Destination: Branch#1, Branch#2
Protocol: <whatever>
Users: <whatever>

You could also include the Internal and LocalHost in the same rule if you
chose.
Source: Internal, LocalHost, Branch#1, Branch#2
Destination: Internal, LocalHost, Branch#1, Branch#2
Protocol: <whatever>
Users: <whatever>

You need to keep security in mind and weight the difference between
convenience and necessity.

If you are using a Remote Access VPN I don't think it is possible,..that
"model" is not intended to be used that way.
