Hey im new in the forum =)
Sory to bother you all and sory for my english.. im from Argentina.

Well i bought this router and i cant make it work, someone can help me?
I tried to configure ir by SDM but i cant get the pcs to navigate internet. The topology would be somwthing like this :
- Routers ip (192.168.1.41).
- lan connected through fe0 -> ip range 192.168.1.1 - 192.168.1.130
- WAN connected through fe4 (wan port) with static ip 201.253.xxx.xx /29 with d. gateway 201.253.xxx.xx This cable comes from a router provided by the isp connected with a G.SHDSL modem (3mbps)

- Dns provided by ISP (i dont remember them right now)

I just want to get it to work with a basic config and then configure firewall and security win the SDM. But putting this data in the SDM doesnt work and i dont know why. Theres no space to put the default gateway so i thught it was thay tge problem, but i put in the CLI "ip route 0.0.0.0 0.0.0.0 201.253.xxx.xx" and it worked but tooo slow, and many pages didnt open.
Well... if someone could help me i would appreciate it very much :)
Ty all

I'm probably not qualified to answer your qestions however...
first don't ever post encrypted passwords!

second: I don't use VLANS but I think you need to give FE0 an internal IP address.

Third: instead of "IP ROUTE 0.0.0.0 0.0.0.0 FE4" I think you need "IP ROUTE 0.0.0.0 0.0.0.0 x.x.x.x" where x.x.x.x is your ISP defualt gateway
 
Thanks for your reply gigabyte. I tried changing what you´ve said and it works, but extremely slowly and algo i cant enter most web pages :S :S any ideas?

TY!!
 
Your config, while far from perfect, should work fine. It shouldn't be any faster / slower than what you had previously.

The fe0-3 interfaces are just switch ports, so there's no IP addresses to configure on there.

What does "show interface f4" show? This will let you check the interface for errors and the like.
