[HELP] ASA 5505 w/ Verizon DSL in Cisco http://www.dslreports.com/forum/r23309161 en Tue, 09 Feb 2010 16:53:45 EDT Tue, 09 Feb 2010 16:53:45 EDT Re: [HELP] ASA 5505 w/ Verizon DSL http://www.dslreports.com/forum/remark,23502296 TROLL131313 : I would have to agree that your MTU setting is probably the issue.

I would set you MTU inside and out side to 1492 and see if it works.

Some times because of noise issues, you might even have to set it lower, like I had to when I Verizon DSL. I had to set my MTU size down to 1460 to stop the fragmented packets.

Here is a link on testing and setting up the MTU for DSL.

If this dose not work for you, I would open a TAC support case. There might be an issue with PPPOe with certain firewall settings.]]> http://www.dslreports.com/forum/remark,23502296 Wed, 16 Dec 2009 21:18:43 EDT Re: [HELP] ASA 5505 w/ Verizon DSL http://www.dslreports.com/forum/remark,23499297 elnino :

Dear Ciscouser, were you able to slove the problem if you did please could you expalin how did you sloved it, i have the same issue. if you can post new configuration will be great.

Thank you
The above config looks like it should work minus maybe an MTU issue because of DSL. If you're having a problem, please create your own thread and post the running config of your ASA.]]> http://www.dslreports.com/forum/remark,23499297 Wed, 16 Dec 2009 12:40:19 EDT Re: [HELP] ASA 5505 w/ Verizon DSL http://www.dslreports.com/forum/remark,23497763 anon : Valjonx,

Unfortunately no I never got this working, I ended up putting the firewall in transparent mode and sacrificing the features of routed mode.

If you get it going, please share :)]]> http://www.dslreports.com/forum/remark,23497763 Wed, 16 Dec 2009 08:17:14 EDT Re: [HELP] ASA 5505 w/ Verizon DSL http://www.dslreports.com/forum/remark,23497686 Valjonx : Dear Ciscouser, were you able to slove the problem if you did please could you expalin how did you sloved it, i have the same issue. if you can post new configuration will be great.

You will need to put the subnet/gateway info in. ]]> http://www.dslreports.com/forum/remark,23309303 Sun, 08 Nov 2009 08:49:11 EDT [HELP] ASA 5505 w/ Verizon DSL http://www.dslreports.com/forum/remark,23309161 anon : Hello all,

I'm pretty decent in the world of Cisco but I'm having trouble getting traffic to flow out with a ASA 5505 on Verizon DSL. I have a static IP with Verizon and I'm using their Westfall 7500 modem/router as a routed bridge into my network.

The data flow goes likes this: Westfall 7500 > Cisco Catalyst Switch > ASA 5505

The switch has a inside and outside VLAN. The router and the outside interface on the ASA reside in the outside VLAN, everything else is on the inside VLAN.

At this point I have a very basic configuration, I think the issue may reside in one of two areas:

1) The outside interface is set to the static IP that Verizon gave me
2) I'm routing the outside interface to the Verizon gateway, basically my static IP but it ends in .1 (route outside 0.0.0.0 0.0.0.0 xxx.xxx.xxx.1)

Should I be routing the outside interface elsewhere? Are there any other issues that anyone can think of?

Just as a side note, all the speed/duplex settings seem to match, I've had trouble with that in the past...

Thanks]]> http://www.dslreports.com/forum/remark,23309161 Sun, 08 Nov 2009 06:44:24 EDT
