[Solved] VMWare Workstation Routing Problems

Agarax · Mar 17, 2014, 12:46 AM

I'm currently having trouble getting a basic install of pfSense to route traffic from two virtual networks on VMware. Below is the setup:

ISP<==> Router <=Physical Network=[10.0.0.0/24]=> Physical Linux Workstation <=VMware's Default NAT (/dev/vmnet8) [10.0.8.0/24]=>pfSenseVM<=Lan Segment [192.168.200.0/24]=>Linux VM.

I installed pfSense using the default configuration but it seems to have problems routing to the internet. Below is some output.

Below is an ifconfig output from a shell on the pfSense VM:

em0: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500
	options=9b <rxcsum,txcsum,vlan_mtu,vlan_hwtagging,vlan_hwcsum>ether 00:0c:29:b0:1a:66

A traceroute from the Linux VM to the internet:

traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets
 1  pfSense.localdomain (192.168.200.1)  0.314 ms  0.182 ms  0.182 ms
 2  pfSense.localdomain (192.168.200.1)  0.223 ms  0.217 ms  0.219 ms
 3  pfSense.localdomain (192.168.200.1)  0.212 ms  0.217 ms  0.213 ms
 4  pfSense.localdomain (192.168.200.1)  0.208 ms  0.318 ms  0.593 ms
 5  * * *
 6  * * *
 7  * * *
 8  * * *
 9  * * *
10  *^C

A traceroute from the pfSense box to the internet:


[2.1-RELEASE][root@pfSense.localdomain]/root(2): traceroute 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 64 hops max, 52 byte packets
 1  localhost (127.0.0.1)  0.247 ms  0.137 ms  0.134 ms
 2  localhost (127.0.0.1)  0.165 ms  0.170 ms  0.200 ms
 3  * * *
 4  *^C

And, finally, a traceroute from the same Linux VM as before but this time connected to the same NAT network as the pfSense VM:


traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets
 1  10.0.8.2 (10.0.8.2)  0.162 ms  0.108 ms  0.095 ms
 2  10.0.0.2 (10.0.0.2)  0.383 ms  0.319 ms  0.230 ms
 <snip>14  google-public-dns-a.google.com (8.8.8.8)  20.406 ms  20.233 ms 72.14.234.55 (72.14.234.55)  21.329 ms</snip>

Anyone have any ideas of what it could be?

Thanks

Solved: Turns out that sometimes if you go through the setup too fast you can end up setting the LAN interface as the default gateway … Fix is deleting it from System: Gateways.
