Hi, I implemented a zywall behind router cisco827-v (that is because I tought cisco827-4v has not enough memory to upgrade to an ipsec 3des supported IOS.. then I found it even doesn't exist) to set up a vpn. However since router cisco827-4v has nat configured I read zywall need that router has ipsec pass-through supported. I'm sure ipsec is not supported but ipsec pass-through? here is a show version:
IOS (tm) C820 Software (C820-OV6Y6-M), Version 12.2(8)YN, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1)
the second question is: how it is possible that ipsec 3des IOS for cisco827-4v doesn't exist!? ..at least I haven't found it.
why don't you try the cisco feature navigator? Go to http://www.cisco.com/go/fn/ . It seems to exist an IOS that you searching for (12.3(9) IP/FW PLUS IPSEC 3DES c820-k9osy6-mz.12.3-9.bin RAM:24mb FLASH:8mb)
