hi,everybody. My envirment is: the outside interface of pix 525 is connected to the fibre-ethernet transceiver ,no router availble, and the dmz interface of the pix is connected to several severs like www,dns,etc. The inside interface is connected to the lan, no proxy availble. When I finished my configure, I met some problem: 1 The dmz servers traffic can not be out. And at the same time,they can not ping the outside interface address correctly. 2 the inside lan nodes can not ping the dmz interface address,but can ping other server in the dmz correctly.
I know I should use the nat commands to bring the traffic of dmz to the outside, but since the outside address provided by the isp are private ones, so I have to use NAT (dmz) 0, but why the dmz traffic can not be out? I hope the design is not wrong. the following is my config,help me,please. sh conf : Saved : PIX Version 6.0(1) nameif ethernet0 outside security0 nameif ethernet1 inside security100 nameif ethernet2 dmz security50 nameif ethernet3 intf3 security15 nameif ethernet4 intf4 security20 enable password 8Ry2YjIyt7RRXU24 encrypted passwd 2KFQnbNIdI.2KYOU encrypted hostname pixfirewall fixup protocol ftp 21 fixup protocol http 80 fixup protocol h323 1720 fixup protocol rsh 514 fixup protocol smtp 25 fixup protocol sqlnet 1521 fixup protocol sip 5060 fixup protocol skinny 2000 names access-list acl_in permit tcp any host 202.99.33.69 eq smtp access-list acl_in permit tcp any host 202.99.33.72 eq www access-list acl_in permit tcp any host 202.99.33.66 eq domain access-list acl_in permit tcp any host 202.99.33.67 eq domain access-list acl_in permit icmp any any access-list ping_acl permit icmp any any pager lines 30 interface ethernet0 auto interface ethernet1 auto interface ethernet2 auto interface ethernet3 auto shutdown interface ethernet4 auto shutdown mtu outside 1500 mtu inside 1500 mtu dmz 1500 mtu intf3 1500 mtu intf4 1500 ip address outside 210.82.34.29 255.255.255.0 ip address inside 192.168.4.1 255.255.255.0 ip address dmz 202.99.33.254 255.255.255.0 ip address intf3 127.0.0.1 255.255.255.255 ip address intf4 127.0.0.1 255.255.255.255 ip audit info action alarm ip audit attack action alarm no failover failover timeout 0:00:00 failover poll 15 failover ip address outside 0.0.0.0 failover ip address inside 0.0.0.0 failover ip address dmz 0.0.0.0 failover ip address intf3 0.0.0.0 failover ip address intf4 0.0.0.0 pdm history enable arp timeout 14400 global (dmz) 1 202.99.33.73 netmask 255.255.255.0 nat (inside) 1 192.168.4.250 255.255.255.255 0 0 nat (dmz) 0 202.99.33.0 255.255.255.0 0 0 static (dmz,outside) 202.99.33.69 202.99.33.69 netmask 255.255.255.255 0 0 static (dmz,outside) 202.99.33.72 202.99.33.72 netmask 255.255.255.255 0 0 static (dmz,outside) 202.99.33.66 202.99.33.66 netmask 255.255.255.255 0 0 static (dmz,outside) 202.99.33.67 202.99.33.67 netmask 255.255.255.255 0 0 access-group acl_in in interface outside access-group ping_acl in interface dmz access-group ping_acl in interface inside route outside 0.0.0.0 0.0.0.0 210.82.34.25 1 timeout xlate 3:00:00 timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 rpc 0:10:00 h323 0:05:00 sip 0:30:00 sip_media 0:02:00 timeout uauth 0:05:00 absolute aaa-server TACACS+ protocol tacacs+ aaa-server RADIUS protocol radius no snmp-server location no snmp-server contact snmp-server community public no snmp-server enable traps floodguard enable no sysopt route dnat telnet timeout 5 ssh timeout 5 terminal width 80 Cryptochecksum:3be86ece2c90058e0c9190f986717d63 pixfirewall# Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=33287&t=33287 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
