I recently installed IPCOP and everything was working fine.Then suddenly I could not send mail,
but I could receive mail. Thinking that my ISP was having problems I ran
a traceroute and noticed that the first hop was to 10.1.7.1 (from my
firewall through a linksys router)

traceroute linuxquestions.org

As you can see from above this is very strange!!!! The output from my route command is:

route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.25.241.0 * 255.255.255.0 U 0 0 0 eth1
10.25.240.0 * 255.255.255.0 U 0 0 0 eth0
default 10.25.241.254 0.0.0.0 UG 0 0 0 eth1

I have looked at resolv.conf and it only has my local host. The above output was from my firewall.
I am also including the output of route from one of my server going
through the firewall along with a traceroute:

route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

Not sure what your question is...... Looks OK. But I have never seen an
MPLS entry in a traceroute listing.
What traceroute are you running here......?
