ISA Server 2004 sp2
This could be tricky to explain, so please look at the basic diagram of my network in the attachment.
With Firewall Client 'ON', then a client on 10.10.1.100 cannot connect to the SQL Server by creating an ODBC ... but turn 'OFF' the FWC and it can. Same for RDP protocol. However, PINGING works across the switch regardless.
So, to my not-very-knowledgeable brain it looks like any non-standard protocols are being routed out to the ISA Server regardless of the local routing table.
Go easy on me ... i'm a bit of a 'jack of all trades' but wondered if there was a way to tell FWC routes - I want any traffic bound for 192. to go via the switch ... or perhaps I should I be adding the other network to the ISA Server somehow.
Please advise best practice (with what I have here!)
