Odd ping problem 1

[TomLet]

Hello everyone,

Here's the issue. I have a new 2811 with 3 interfaces setup as follows:

FastEthernet 0/0: x.x.81.1/24
Secondary x.x.26.97/27

FastEthernet 0/1: x.x.x.38/30

Serial 0/0: x.x.x.46/30

FastEthernet 0/0 is my LAN interface. I can connect to the secondary IP but not the primary.

FastEthernet 0/1 is an ethernet to SONET internet connection that I can ping.

Serial 0/0 is a T1 WIC internet connection I can ping.

I am using BGP for the internet connections. I am trying to figure out why I can't connect to the primary IP on FastEthernet 0/0. It will not connect on telnet, ping, http or anything else I try. Any help will be appreceated!

Thanks,
Tom

Tom,

Can you ping the interface from the router? And since it's a new router, have you already done an 'ip routing?' <- just checking.

What subnet is your workstation on? Maybe you can post a sanitized version of the config?

Try this:

access-list 157 permit icmp any any
debug ip packet detailed 157
term mon(if telnetted in)

ping from the workstation and see what you get.

rtfmdude,

I figured it out. Your post helped so you get a star! When I was setting the router up initially it was behind my firewall with its new IP block. To communicate with it I gave my workstation an address in the same range. When we went live with the router and put it on the otherside of the firewall I forgot to remove the seconday address from my workstation so the workstation thought it was a local net and wasn't forwarding the packets to the gateway. Stupid! The question about my subnet reminded me, removed the secondary address on the workstation and now everthing is fine. Thank You for the nudge!

haha - good! my past stupidity CAN benefit me in the future! (if only I can convince a certain ex-girlfriend of the same)

I was thinking, "man, if this guy's running bgp, then he can't have made a dumb mistake..."

It appears that even bgp-users are mere mortals! glad it's working.
