Pix 515e VPN Config Question

ok well im a noob when it comes to 515e PIX. Let me tell you how my current setup is. Pix is doing dhcp (10.25.19.x network). My vpn pool is 172.16.38.100 /27. I can get connected to the VPN using ipsec, and i get a valid ip, but i cannot access/ping any hosts on the 10.25.19.x subnet. heres my config. I have the debugs if you all wanna check em out.

I've only worked with Network Extension VPNs not a client side pool and I don't time at the moment to dig up the reference material but shouldn't there be a translation between your VPN pool and the private pool?

Those 10s are DHCP'ed to hosts on the inside interface network?

Nothing is getting into the inside network unless you explicitly allow it.

You can also NAT them in.

I don't see either configuration..... but I am reviewing like the wind for my lab exam..... so I don't have time to ponder the config (other than hope I don't see it on the Lab Exam

)

access-list inside_outbound_nat0_acl permit ip 10.25.19.0 255.255.255.240 172.16.38.96 255.255.255.224

This wouldnt allow it ?? dammit wheres my pix book

yea i meant you mike.. lol

mikej412

Isn't it source first in the ACL? Or are you trying to confuse me for the lab exam?

The 10s are a higher security interface so they should be able to get out from inside without a problem.

You'd need the ACL to get from the VPN pool through the higher security inside interface.

Great -- now you got me all confused and now I'll have to stay up all night and re-read the Doc DVD.... just kidding.

I was already planning to do that anyway.... just kidding again.

I'm really planning to memorize all the IDS signature configurations tonight. Ha ha -- got you again!

I'm done studying and plan to just drink until my Lab exam.

Okay -- enough jokes.... back to my IDS Sensor.... I'm near the end of the Lab Blueprint and trying to figure out what "Advanced IDS features" could be....

thisisalex02

lol are you drunk mike ! ! lol

so u think i need to flip around those private pools in the acl so that it looks like

access-list inside_outbound_nat0_acl permit ip 172.16.38.96 255.255.255.224 10.25.19.0 255.255.255.240

Put down that blueprint for a bit.. grab a beer.. and help me out..

When u got lab ?
