site to site asa 5200 to ISA 2006 connection drops after a few min
I have a tunnel established site to site and the only way we can get it to negotiate is for the ISA site to ping the ASA site. At that point Im able to ping his internal and vice versa but after a few minutes of no activity the connection drops and he has to ping me again. Im not familiar with ISA but he says there is no keep alive setting like with Cisco. Any ideas on how to make the tunnel stay active? thanks in advance
