I've got a 1721 with an ESW-4 Switch attached to it. I decided to use a range of 192.168.0.0/26 as my homenet for normal clients. NAT overload on my outside interface (fa0) does the trick to bring my clients into the net. So far, so good. Now I decided to assign a secondary address to my VLAN (using192.168.0.64/28), anticipating throwing my server into another subnet (and subsequently into another VLAN) and it is there, where I'm facing a problem.
My Clients in the first subnet are now having troubles. When I start to ping, I can see about 50% loss for the first few minutes, about 30% after that. Funny thing is: After about 20 Minutes, there is nearly no loss anymore.
Deleting the secondary IP solves that problem instantly.
Can someone give me a hint of what went wrong? Is this setup impossible? Is there another possibility with a built-in-switchcard, that resembles a router on a stick more closely?
Thanks for any advice luke
