New Install - ICMP Host Unreachable from gateway

Question

Hi team,
I'm configuring a new solaris x86 box for the first time in a long time and I'm running into a problem that has me stumped.
I just installed Solaris 10 v7 on a P4 Dell box with an intel pro1000 adapter loaded.
Installed using ZFS and install went well. I set a static IP of 192.168.1.70 on a proper 192.168.1.x lan.
After install, everything seems to work fine but cannot ping a FQDN such as www.google.com, etc.
at first, I tried to join a local domain - maxximgroup.com and my computer name is set to sunzilla.
Here's my network config files;
sunzilla is set up with static IP = 192.168.1.70
# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 192.168.1.70 netmask ffffff00 broadcast 192.168.1.255
ether 0:1b:21:27:56:2c
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1
inet6 ::1/128
e1000g0: flags=2004841<UP,RUNNING,MULTICAST,DHCP,IPv6> mtu 1500 index 2
inet6 fe80::21b:21ff:fe27:562c/10
ether 0:1b:21:27:56:2c
And /etc/hosts shows host name sunzilla associated w/ 192.168.1.70...
# cat /etc/hosts
# Internet host table
::1 localhost
127.0.0.1 localhost
192.168.1.70 sunzilla loghost
And my resolv.conf file shows my internal DNS routers as well as a 3rd I added (4.2.2.2) just in case...
# cat /etc/resolv.conf
domain maxximgroup.com
nameserver 192.168.1.20
nameserver 192.168.1.22
nameserver 4.2.2.2
search maxximgroup.com
I noticed the /etc/defaultrouter file was MISSING... so I created one pointing to my router...
# cat /etc/defaultrouter
192.168.1.1
And finally, I checked the /etc/nsswitch.conf file and it does indeed show hosts & ipnodes --> files & dns ...
# cat /etc/nsswitch.conf

netgroup: files
automount: files

I can ping local IP addresses ...
# ping 192.168.1.1
192.168.1.1 is alive
But not external addresses ...
# ping 67.15.211.8
ICMP Host Unreachable from gateway sunzilla (192.168.1.70)

^C#
and naturally, I can ping a FQDN either (confirmed to be pingable on a computer on the same lan) ...
# ping mycloud.local
ping: unknown host mycloud.local
Can anyone provide some guidance pls?

Thanks Robert. You were absolutely on the right track. It turns out that in my "rush" to get my new ZFS "toy" up and running, during the install, I gave Solaris a static address but told it to automatically find the gateway. Oops! When solaris 10 installed, it correctly decided that since it had a static IP, it should assign the gateway as itself! So, naturally, when I ran netstat -m, It showed my gateway as myself! 192.168.1.70 sunzilla.
I'm used to running Solaris on a Sparc platform and I'm a bit uncomfortable with reboots and I figured there would surely be a network restart command somewhere. After finding out that things have now changed in Solaris 10 quite a bit from Solaris 8, I just decided to init 6.
After the system came up, everything was happy : -)
So again, thanks to Robert for helping save the day!
