Problem with 1720 and Internet access -- need help 1

Hi,

I've poured over many threads trying to find one that contains the solution to my problem. No luck yet :(

I am configuring a new 1720 router. The internal LAN (192.168.x.x) is working fine. The router has a WIC-1enet (ethernet 0) being used to connect to the cable modem from ISP.

Internet >> Cable modem >> Cisco 1720 >> LAN

The ISP assigns a dynamic address. Ethernet 0 is picking up an address just fine. The router is able to ping the ISP gateway and all internal LAN addresses but that is it. I have no success pinging the ISP dns or any other website. Obviously I'm not able to get on the internet from any LAN node.

Here is the current running-config:

btw: I pieced this configuration together using ConfigMaker and from other bits I've seen in other configs on tek-tips.

I realize using access-group 110 (permit any any) is overkill and redundant but I am at a loss.

Your help is very much appreciated!

does your cable modem require a dialer interface configuration to work properly. mine does not? just curious. try changing the default route to

ip route 0.0.0.0 0.0.0.0 ether0

No, I don't think a dialer is required. I'll try your suggestion, thx.
 
I changed the ip route to eth0 and removed the dialer. Still experiencing same problem (see beginning thread).

Here is new config:

now you need to change the nat statement to reflect the change

ip nat inside source list 1 interface Ether0 overload

what default gateway ip address is the router receiving via dhcp

this is a weird one. this config should work. i will look into it more. i have a lab here i will config up and check

show interface ethernet 0

show interface fastethernet 0/0

please post

ok. lets get the actual ip address of the default gateway from the cable modem provider. then instead of

ip route 0.0.0.0 0.0.0.0 ethernet 0

lets try

ip route 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx with x being the ip address of the gateway from dhcp

i think that will work since just sending it out the interface will send it into a point to mulitpoint network and it won't necessarily know who its default gateway should be so its getting lost. if it was a point to point connection that statement would work. my bad. lets try that and see what happens. try pinging a host name and an ip address on the outside instead of checking with internet explorer.

also if you could do a traceroute from a pc and post

as well as a ping from the router using the source address as ethernet 0 source address. that will verify connectivity.

thanks. sorry for the many posts. just working through the problem without being in front of the box is more difficult. we'll get it figured out

try the default route thing first.

###It appears that some packets are being dropped. Any recommendations for clearing that up? Also, what is recommended for access-list? Thank you very much for your help!!!###
 
ip route 0.0.0.0 0.0.0.0 Ethernet0


remove this statement using

no ip route 0.0.0.0 0.0.0.0 Ethernet0


you are load balancing across two default router. one works one does not. hence you are dropping half of the packets. remove that statement and you will be in business. retest and let me know.

Hi lui3,

Thanks for your help!

The configuration is routing Internet traffic. However, it doesn't seem to be working as fast as my old linksys router. Sometimes it takes up to ten seconds to open a webpage or will time out. I'm not sure if there is something I can do with the configuration to speed up web browsing. Let me know, thanks again!

Good job folks.

Now, I have a question about setting default routes to Interfaces instead of IP's.

In some simple destination load balancing examples I've seen folks recommend using:

ip route 0.0.0.0 0.0.0.0 Ethernet0 [metric]
ip route 0.0.0.0 0.0.0.0 Ethernet1 [metric]

However, as you say LUI3 this only works for point-to-point connections (T1, etc?) So, what is an accepted and workable solution for load balancing across two Ethernet links?

Thanks a bunch,
Ned

Hi lui3,

Thanks for your help!

The configuration is routing Internet traffic. However, it doesn't seem to be working as fast as my old linksys router. Sometimes it takes up to ten seconds to open a webpage or will time out. I'm not sure if there is something I can do with the configuration to speed up web browsing. Let me know, thanks again!

peter,

i am getting similar responses to the websites when i try to ping them as well.

is shaky at best


all time out when trying to ping them

must be their firewall blocking icmp replies. this is common. you can't ping our sites either but you can access the webpages. i don't think there is anything wrong with your setup here. so not much to improve. you might want to check the order of your dns search in your ip settings. if you have a server that is slow to respond or is failing it will take a while to resolve webpages. from the router however things look normal.

try pinging from interanl hosts and see if the symptoms change or get worst. it could be a LAN issue.
