Allow incoming HTTP & FTP Traffic

[smokey7244521]

I have a Pix 515 and am needing to allow incoming traffic to a FTP & Web Server. Below are 2 different ways i have tried, and also my config. Thanks in advance

static (inside,outside) 68.188.127.9 10.1.16.24 netmask 255.255.255.255 0 0
conduit permit tcp any host 68.188.127.9 eq ftp
conduit permit tcp any host 68.188.127.9 eq http
access-group WebServer in interface outside




static (inside,outside) 68.188.127.9 10.1.16.24 netmask 255.255.255.255 0 0
access-list WebServer permit tcp any host 68.188.127.9 eq ftp
access-list WebServer permit tcp any host 68.188.127.9 eq http
access-group WebServer in interface outside

I think Networkghost said this in a earlier post - you are going want to convert the conduit and outbound commands to ACL's. Cisco has a tool but it isn't perfect.

http://www.cisco.com/en/US/ts/fn/200/fn26895.html

Give this a try -
You can use object groups to limit the ACL lines

object-group service allowed-services tcp-udp
description Services allowed outbound after lockdown
group-object webservices
port-object eq 20
port-object eq 21
port-object eq 22
port-object eq 23
port-object eq 25
port-object eq 53
port-object eq 80
port-object eq 110
port-object eq 123
port-object eq 143
port-object eq 443
port-object eq 3389
port-object eq 8383
port-object eq 9001

and then
access-list inside-to-outside permit tcp 10.1.0.0 255.255.0.0 any object-group allowed-services
access-list inside-to-outside permit udp 10.1.0.0 255.255.0.0 any eq 53

access-list outside-to-inside permit tcp any host 68.188.127.9 eq 20
access-list outside-to-inside permit tcp any host 68.188.127.9 eq 21
access-list outside-to-inside permit tcp any host 68.188.127.9 eq 80
access-list outside-to-inside permit tcp any host 68.188.127.9 eq 443
access-list outside-to-inside permit tcp any host 68.188.127.10 eq citrix-ica

access-group outside-to-inside in interface outside
access-group inside-to-outside in interface inside

That looks like it should convert all your conduits to ACLs. Remove your conduits and outbounds and give it a try but be sure to back it up in case it doesn't work.
