Need help with 2501 and copying flash to tftp

zenzen

OK, some background on what I have first...Just got a 2501 router from ebay along with a 3640. I had an 851w router already and that's what I have my cable internet connected to.

Now I am just a beginner and I want to back up my 2501's IOS just in case and as soon as possible so I figured I'd just connect an ethernet cable from the 2501 into my 851w fa 3 port and see if it'd find the tftp server I have on my PC.

My PC is connected to fa 0. 2501 > 851w < pc

I thought maybe I need a crossover cable but I tried to ping my 2501 from my pc and I can do that. I can also ping BVI1 on my 851w, which is 192.168.1.1. My tftp is on 192.168.1.100. I have backed up my 851w so the tftp is tested and working.

Router(this is the 2501)>en
Router#ping 192.168.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/1 ms
Router#ping 192.168.1.100

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.100, timeout is 2 seconds:
this ping timed out

I guess the first packet to .1 failed cause of arp. The 2501's config has been erased cause it came with a pw, and so far I've only configured the IP address to be in the same subnet.

there are some access lists on this 851w and I'm not sure if this is the cause

Standard IP access list 1
10 permit 192.168.1.0, wildcard bits 0.0.0.255 (337853 matches)
20 permit 192.168.2.0, wildcard bits 0.0.0.255 (145825 matches)
Extended IP access list Guest-ACL
10 deny ip any 192.168.1.0 0.0.0.255 (9 matches)
20 permit ip any any (3223997 matches)
Extended IP access list Internet-inbound-ACL
10 permit udp any eq bootps any eq bootpc (742212 matches)
20 permit icmp any any echo (393 matches)
30 permit icmp any any echo-reply (302 matches)
40 permit icmp any any traceroute
50 permit gre any any
60 permit esp any any


When I got this router I knew nothing about configuring cisco stuff so I found this config maker that used excel. I managed to configure everything but wireless so I looked for a config example and eventually found that. the config maker did all this access list stuff. I don't have a full understanding of these yet. Btw, what do the matches mean, just that a count of the stuff that is permitted or denied?

Yeah any help with getting this to work is appreciated, I know this probably isnt' the best laid out question ever but I kept thinking of stuff and figured out I could ping bvi1 in the middle of all this.

WOW ... you better work on your question ... Hope I never get one like this on an exam!!!

Like ... what exactly is your problem when trying to copy to TFTP?

I can ping bvi1 on my 851 from my 2501 router. but I can't ping my PC that's connected to my 851 router, and therefore I can't copy my flash to the tftp server

seems my 2501 can see my 851 router but can't get through to my pc, I dunno why

I'd be the best test maker ever, nobody would ever pass hahaha

Do you have your computer configured statically with an ip address and a default gateway. Even if you ping your computer and it's actually up but it doesn't have a route back to the machine that pinged it, you will not receive replies.

zenzen

well my 851w is acting as my dhcp. I can actually ping my 2501 router's ethernet interface from my PC, but I can't ping from my 2501 router to my PC. I have no idea why not


ah I see what you had thought about, maybe it's getting there but my computer was dropping it or somethin. somehow that isn't it though. it's really annoying me, I could just plug up the 2501 to my NIC i guess but I won't learn anything that way.

Define your objectives ... Studying for CCENT / CCNA?

Maybe start from the beginning?

RK

zenzen

well I'm just studying for ccna right now

and this wasn't even supposed to be part of the studying. I just wanted to copy the flash to my tftp server so I'd have a backup and I cannot figure out why I can't do it.

wow this is quite discouraging, I'm nearly finished with todd lammle's ccna book and I can't even get my router to ping my PC lol

Can you post your 2501's config?

And the config on the other router as well.

You have provided access lists, but haven't told us where they are applied.

So it's probably a PC firewall issue. Either disable it to confirm, or configure it to allow local machines (or the router specifically) to access your PC.
