Need help with dhcpagent errors


I have been having trouble with my OpenIndiana server for the past few weeks. The dhcpagent has been acting up and displaying these errors on both stderror and /var/adm/messages. This is what it is displaying in /var/adm/messages:
Code:
Jun 23 16:38:27 Tallac /sbin/dhcpagent[153]: [ID 490758 daemon.error] send_pkt_internal: cannot send INFORMATION-REQUEST packet to server (will retry in 130 seconds): Network is unreachable
Jun 23 16:40:38 Tallac /sbin/dhcpagent[153]: [ID 490758 daemon.error] send_pkt_internal: cannot send INFORMATION-REQUEST packet to server (will retry in 115 seconds): Network is unreachable
Jun 23 16:42:34 Tallac /sbin/dhcpagent[153]: [ID 490758 daemon.error] send_pkt_internal: cannot send INFORMATION-REQUEST packet to server (will retry in 116 seconds): Network is unreachable
Although it states that the network is unreachable I do happen to have a working ipv4 address, which allows me to remote connect to my server. I'm also able to ping remote hosts such as 8.8.8.8. Here is what ifconfig says:
Code:
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000 
e1000g0: flags=1004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4> mtu 1500 index 2
        inet 192.168.1.135 netmask ffffff00 broadcast 192.168.1.255
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1
        inet6 ::1/128 
e1000g0: flags=20002000841<UP,RUNNING,MULTICAST,IPv6> mtu 1472 index 2
        inet6 fe80::1aa9:5ff:fe18:9ab5/10 
e1000g0:1: flags=20002080841<UP,RUNNING,MULTICAST,ADDRCONF,IPv6> mtu 1472 index 2
        inet6 2602:304:b117:659:1aa9:5ff:fe18:9ab5/64
Now I had this same problem on my test server, which is running a newer installation of Openindiana but hasn't been updated since may. For this fix I allowed port 67 to pass in and out of my firewall. Now this fixed my initial issue on my test server. However when I tried it on my actual server, it continues to give out the above errors in /var/adm/messages...

On my actual server I have made new entries in the firewall to allow both ports: 67 and 68, to pass in and out, but the error does not stop. I'm starting to ponder whether or not I should just do a clean install with an updated iso from OpenIndiana. I have had this operating system since august. Its been a great learning experience, and I can do things a more efficient job than when I started with this server.

Here is my firewall rules in question for my test server in /etc/ipf/ipf.conf:
Code:
#Allow DNS Cleunt
pass out quick on e1000g0 proto tcp/udp from any to any port = 67 keep state
pass in quick on e1000g0 proto tcp/udp from any to any port = 67 keep state
These rules are the same in /etc/ipf/ipf6.conf
Here is the last 5 lines in /var/adm/messages on my test server:
Code:
Jun 22 09:40:12 openindiana rootnex: [ID 349649 kern.info] xsvc0 at root: space 0 offset 0
Jun 22 09:40:12 openindiana genunix: [ID 936769 kern.info] xsvc0 is /xsvc@0,0
Jun 22 09:40:35 openindiana pseudo: [ID 129642 kern.info] pseudo-device: devinfo0
Jun 22 09:40:35 openindiana genunix: [ID 936769 kern.info] devinfo0 is /pseudo/devinfo@0
Jun 22 09:40:35 openindiana ipf: [ID 774698 kern.info] IP Filter: v4.1.9, running.
As you can see no dhcpagent messages on my test server.

Here is firewall rules in question on my actual server:
Code:
#Allow DNS Client
pass out quick on e1000g0 proto tcp/udp from any to any port = 67 keep state
pass in quick on e1000g0 proto tcp/udp from any to any port = 67 keep state

pass out quick on e1000g0 proto tcp/udp from any to any port = 68 keep state
pass in quick on e1000g0 proto tcp/udp from any to any port = 68 keep state
Along with the output of ipfstat -hio on my server:
Code:
0 pass out quick on e1000g0 proto tcp from any to any port = http keep state
0 pass out quick on e1000g0 proto tcp from any to any port = 2220 keep state
0 pass out quick on e1000g0 proto icmp from any to any keep state
107 pass out quick on e1000g0 proto tcp/udp from any to any port = domain keep state
0 pass out quick on e1000g0 proto tcp/udp from any to any port = 9000 keep state
5 pass out quick on e1000g0 proto tcp/udp from any to any port = 67 keep state
0 pass out quick on e1000g0 proto tcp/udp from any to any port = 68 keep state
973 block out log first quick on e1000g0 all
140 pass in quick on e1000g0 proto tcp from any to any port = http keep state
2 pass in quick on e1000g0 proto tcp from any to any port = 2220 keep state
236 pass in quick on e1000g0 proto icmp from any to any keep state
0 pass in quick on e1000g0 proto tcp/udp from any to any port = 9000 keep state
168 pass in quick on e1000g0 proto tcp/udp from any to any port = 67 keep state
47 pass in quick on e1000g0 proto tcp/udp from any to any port = 68 keep state
0 block in log first quick on e1000g0 proto tcp from any to any flags FPU/FSRPAU
0 block in quick on e1000g0 from any to any with frag
0 block in quick on e1000g0 proto tcp from any to any with short
0 block in log first quick on e1000g0 proto tcp/udp from any to any port = microsoft-ds
3633 block in log first quick on e1000g0 proto tcp/udp from any to any port = netbios-ns
682 block in log first quick on e1000g0 proto tcp/udp from any to any port = netbios-dgm
0 block in log first quick on e1000g0 proto tcp/udp from any to any port = netbios-ssn
0 block in log first quick on e1000g0 proto tcp/udp from any to any port = 81
0 block in quick on e1000g0 from 172.16.0.0/12 to any
0 block in quick on e1000g0 from 10.0.0.0/8 to any
0 block in quick on e1000g0 from 169.254.0.0/16 to any
0 block in quick on e1000g0 from 192.0.2.0/24 to any
0 block in quick on e1000g0 from 204.152.64.0/23 to any
0 block in quick on e1000g0 from 224.0.0.0/3 to any
0 block in quick on e1000g0 from any to any with ipopts
So my question is: is there any way to fix this issue? Or I am better off by going on a fresh re install of the operating system?

I fixed it, I'm such a klutz, I had a feeling this was it and I was right. So for any one who wants to know the answer to this, here it is.

For some reason when ever you have firewall rules up, dhcpagent will start to freak out. Even though it is maintaining its current dynamic ip address. When you setup a static ip address, the dhcpagent will stop running (as far as I would assume.) This in turn will stop the output of errors on both stderr and /var/adm/messages . For any one who is wondering about setting up a static ip address in Openindiana you can follow this how-to here. I will mark this as solved
