Hi every body,

Sorry for the delayed summary being posted as our we were still testing for
any possible failure, which has
not happened so far. ( its 7 days since firewall was put on production
after installing all the recommended
patches for solaris X86( ver 2.5.1)

The fix was installing all the recommeded patches for 2.5.1 and that has
solved the problem

Thanks a lot all who gave other pointers to check, the details of which are

Now to the original problem:
Has anybody come across or know to have used firewall 1 sucessfully on
> Solaris X86. One of our customer is experiencing problems (

I haven't used FW1 on a x86 machine, but I remember we've had a similar
problem a while ago. The problem on our site was, that the interfaces
weren't configured properly :-(

The cisco thought it was running on a full-duplex ethernet and the SUN
thought it was running on a half-duplex ethernet. That's why I propose
that you check with netstat if you have errors or not on your

I'm running fat, dumb & happy on a 233MHz x86 box with FW-1.
What is the bandwidth of the pipe coming from the 'Net?

Yes, I use Firewall-1 on an x86 box quite successfully - without any
I'm doing NAT too. What kind of pc is hosting this ? How much memory
and how much swap ?

I had Solstice Firewall 2.0 for x86 setup on a Toshiba 430CDT laptop for
demo purposes.  I found it was very slow due to the fact that the PCMCIA bus
is not very fast for transferring data.

If the customer is using an ISA or an EISA bus for there network cards, it can cause some delays, especially when a lot of traffic occurs. The best thing to do if x86 is the only solution is to ensure that the PCI bus is used for both NIC cards and that the NIC cards are of top quality. ie. 3Com. Also make sure that you have a lot of RAM. For example Solstice Firewall 2.0 recommends at least 64MB of RAM. Of course, the more the better. Marco Greene <
