iptables error

[mrj]

I put this command in REDHAT 7.3 and iptables 1.3.0

#iptables -A OUTPUT -d messenger.msn.com -p tcp -j DENY

it create the next error:

iptables v1.3.0: host/network 'messenger.msn.com' not found

I use iptables how HAT

I write iptables -L

I look the next

Chain OUTPUT (policy ACCEPT)
target prot opt source

my NAT i do whit next command

#iptables -t nat -A POSTROUTING -j MASQERADE -o ppp0

I too write DROP for change el DENNY

[adam7979]

#iptables -A OUTPUT -d messenger.msn.com -p tcp -j DENY
iptables v1.3.0: host/network 'messenger.msn.com' not found

configure your firewall's dns properly, or, try to

#ping google.com
