pix506e not working

jefforamma — Mon, 11 Mar 2019 18:39:40 GMT

we have a backup inet connection that i had an old netgear firewall on.

A pix506e free'd up recently so i thought i would put that on the rogers cable connection as it was alot more stable than the netgear one i was using.

I reset to factory defaults on it. Configured just the basics.

However i am unable to ping the outside gateway, or get any internet traffic working at all.

I have tried changing the network cables (they were the ones the netgear had been using fine up to this point)

i tried changing the nic settings to all types (10 1/2, 10 full, etc)

if i put the netgear back on it works fine.

the config looks ok to me but i am not an expert. could really use help here as this is causing me to bang my head all day.

here is the config. any qs or info needed let me know.

Hi Jeff,

Have you tried connecting the PIX again and then rebooting the cable modem? Many cable modems cache the MAC address of the connected device and only allow communication from that device. Power cycling the cable modem after the PIX is attached should allow it to learn the PIX's MAC instead of the Netgear's MAC.

Hope that helps.

hey Mike,

tried that earlier. tried it again just now. no luck though.

i will try leaving both off for an extended period to make sure they are totally cleared out. see if that helps at all.

any other suggestions?

Re: pix506e not working

mirober2 — Mon, 13 Sep 2010 18:50:52 GMT

Hi Jeff,

After you try pinging the gateway from the PIX, do a 'show arp' and see if you have a valid MAC address for the gateway's IP address.

jefforamma — Mon, 13 Sep 2010 19:14:52 GMT

did a ping and show arp. it only shows internal ips, not the exteral with a mac.

tried clearing arp and doing it again but still only shows internal ips in list.

i will try leaving both units off overnight and cycle them up in the morning to see how that goes.

Hi Jeff,

Are you sure the address and netmask information is configured correctly based on what your ISP provides? If you change the interface config to 'ip address outside dhcp setroute', do you get the same IP address and gateway information?

ip address outside 208.97.118.106 255.255.255.248
route outside 0.0.0.0 0.0.0.0 208.97.118.105 1

When you issue "sh arp | i .118.105" you do not show the MAC for the router IP?

enable "debug arp" and ping 208.97.118.105 from the firewall and see what you get. You are able to ping the fierwall interface 208.97.118.106 right?

well..left it off all night. powered up modem this am. then powered up pix.

still no go.

called rogers and they were not any help. they said they could ping it from outside, he reset it remotely. nothing worked.

put the config into ciscos output interpreter and got the following?

WARNING: The following interfaces do not have associated 'route' commands:

inside

The PIX requires a static/default route for any destinations that are not directly

connected to these interfaces, assuming the PIX is not receiving a default RIP

route from a connected router on these interfaces.

TRY THIS: Configure a static/default route for those interfaces that need to access

non directly connected destinations using the configuration command, 'route if_name

ip_address netmask gateway_ip [metric]'.

However I do a show route and see the route there? Not sure what is up.

outside 0.0.0.0 0.0.0.0 208.97.118.105 1 OTHER static

inside 192.168.32.0 255.255.255.0 192.168.32.2 1 CONNECT static

outside 208.97.118.104 255.255.255.248 208.97.118.106 1 CONNECT static

i am not sure what that bottom route is or where it came from. it will not let me remove it either.

i cant set the outside int to dhcp as it is a static ip.

kusankar,

tried the commands you said. here is what came up.

I am able to ping 208.97.118.105 but the PIX isnt'.

ping 208.97.118.105
PING 208.97.118.105 (208.97.118.105): 56 data bytes

That other route

outside 208.97.118.104 255.255.255.248 208.97.118.106 1 CONNECT static

is a connected route. Are you sure the mask is correct?

208.97.118.105 - 208.97.118.110 - valid hosts on that subnet are from .105 to .110. The ip addresses .106 and .105 are valid hosts.

You are not seeing any packets coming from the router towards the PIX's outside interface is my guess.

cap capout int outside

sh cap capout

see if you are seeing any packets coming towards your interface.

jefforamma — Tue, 14 Sep 2010 14:39:44 GMT

ya i can ping the 105 gateway externally from another site as well.

icmp is not enable on the 106 int.

here is the capout when enabled and a ping is done.

14:37:31.334592 arp who-has 208.97.118.105 tell 208.97.118.106

on the asdm i dont see any traffic on outside int

forgot to mention. yes you have all the right subnet info there. i did verify that all from the old firewall and the call with rogers as well.

Re: pix506e not working

Kureli Sankar — Tue, 14 Sep 2010 15:41:53 GMT

Can you call them and ask if they have a static arp configured on the router pointing to the old firewall's MAC address for this IP address .106.

get the mac address of the PIX's outside interface MAC and give that to them so, the router send traffric to this MAC.

Have them check that.
