Hi,
I wonder how to enable a scenario where i have to use two ISP's to share 30/70 load on our internet traffic, have to configure almost 60 internal websites already published using microsoft TMG firewall and connect client VPN connections and site-to-site vpn connections. I know that ASA firewall has limitation when using security contexts. Is good idea that how to achieve this gool?
I previously tried connecting four sites running ASA devices with this fifth site running Microsoft TMG firewall but i was able to connect only two ASA firewalls using site-to-site VPN, though I was able to connect remaining two as well but last two were not able to access ASA-TMG resources. furthermore behavious of two ASA-TMG connected sites was strange: sometime i was not able to access cross site resources from one machine but was able to do so from another machine.
I noticed that two of ASA sites connected with TMG site has different internal IP class (e.g site one 192.168.0.* and site two using 172.16.*.*) while remaining two have same class like the first site e.g 192.168.128.* and 192.168.100.*
Did anyone has experiance connecting TMG-ASA with multiple sites within same IP class scenario?
OR
How to enable same features using Cisco devices as they are on a single Microsoft TMG?
Best,
