Hello,
we are having a sharepoint 2010 3 tier-farm:
1st tier: Apcahe server (reverse proxy) - with internet connection.
2nd Tier: 2 Web front ends & 2 application servers & indexing server - no internet connection.
3rd Tier: SQL servers - no internet connection.
we need to use the federated search for external content source that for sure require internet. 1st tier server shouldnt have communication with 3rd tier (that what made us put all the sharepoint server in the 2nd tier from the first place). the problem is we cannot allow internet access on the 2nd tier neither move the servers to the 1st tier of course.
what are the possible solutions for such case to use federated search from external content sources.?!
Appreciate your help.
