I have a TZ170 up & running, Needing to replace that with a NSA 2400. Do do this I had two laptops plugged into each firewall and just went line by line to setup the NSA 2400. I have a cisco 1721 router behind the 2400. the Lan on the cisco E0 is 10BT at full-duplex. as with the TZ170 i manually changed the settings in the NSA to 10-FDX.
Everything works, e-mail, can reach the internet looks greats.
I go to log into the NSA and it takes 5+ min. to log-in. once I do log in it times-out. I can plug my cable from my laptop directly to the NSA X0(Lan) change my subnet and bam. it's faster than you can blink.
What would casue this? & why? i've checked the duplex / network speed setting in my cisco config file? in setting up the NSA i've noticed were it has a check box for reflective rule? on the NAT policy & Netwrok interface. do I need to confige a reflective rule for the X0 lan side IP?
