Yes, some routers, mostly the older WRT54G types. I don't think the new routers support loopback, not without using a hacked firmware.
Since I'm changing, might as well get a Gigabit N one, it's sad, I would love to get 3Com routers but guess what, HP BOUGHT OVER 3COM !!!
Maybe it's more of a feature that many people don't need, but for those who need, it's extremely important.
I don't think that is true. "Many DSL routers/modems prevent loopback connections as a security feature. "
What kind of security concern there is? Ok, for router, Adrian suggested Linksys 320N, if I flash this to DDWRT, there is loopback support right? What about modem, I know any cheap modem will do, but if anyone have any suggestion, i will gladly hear it.
I don't think you are supposed to find this feature in consumer-grade routers anymore. If you want it, you will have to move up to enterprise-grade routers.
The WRT-320N is definitely cheaper. It's considered to be an obsolete model, replaced by the E2000. AFAIK, it's only sold in technologically-backward countries like Malaysia. FYI, I don't think karhoe has much of a choice. The last time I went to Low Yat Plaza, they only had the E1000. The E2000 and E3000 have "yet to arrive"...
The E2000 doesn't look like an enterprise level though, seems like we are paying for 'aesthetic' value. I would want to have the antenna poking out LOL But E2000 + DDWRT can solve it right?
When? Must be quite recent, because when I went to purchase my WRT-320N, there was no E2000 or E3000 in the entire Low Yat Plaza!
