I'm experienceing a wierd problem with ASL. (version 3.216, latest updates)
It's running on a brand new Dell Poweredge 350 with 4 integrated 10/100/1000 NIC's.
It is protecting a NT4.0 LAN with Exchange 5.5 and most recent service packs.
SMTP Proxy and DNS Proxy are enabled, as is PPTP (RoadWarrior).
PPTP is another problem altogether...
Basically, the LAN users will be able to surf and send and recieve email fine until some point when all name resolution fails. Cannot ping names from WebAdmin even though the DNS entries in DNS Proxy are correct. Coincidentally, I cannot access WebAdmin from a remote location OR ping /tracerout to the external IP (interface).
I had to create a Packet Filter Rule allowing DNS from Internal to Any and make sure the clients have an alternate DNS server incase the Proxy DNS forwarding fails. What gives?
Stopping and starting the DNS proxy service NOR rebooting ASL helps. I don't really know which logs to refer to for analysis, nor what to do once I did know. I'm aware that SQUID is somehow involved in this but have no experience with it.
Can anybody shed some light on this for me? I'm not a newbie, but I AM a grasshopper in a world of masters, so i humbly ask for help....
Many thanks, in advance.
