I have a problem with accessing a couple of websites on our network. I have identified it to be due to the fact the servers are sendning packets that exceed the MSS advertisied by client.
I recall that this is an issue which started in PIX version 7.
I also recall someone telling me that a "tick box" was added to ASDM to allow the firewall to pass packets that exceed the MSS - and that a "simple" command can be issued to allow this action to commence.
I cannot find the "tick" box in ASDM nor can find the refernce to the command.
