Some good detail in there. I also found some useful information here MSS Problems with Sun PPPoE . Additionally, I reviewed my Linux router config to see what may be "working" and found that it's likely that the following firewall rule was addressing the issue I'm now experiencing with Solaris.
Too bad it wasn't that simple with the Solaris setup . I'll attempt to tune the Solaris setup and see how I make out.

It's working now...and appears to be performing, but is it optimal?...I'm not sure yet. For those who wish to tackle using Solaris as a firewall/router against a PPPoE connection, I'll put my details here.
By default, the negotiated MTU over PPPoE is going to be 1492.
Using the 1492 MTU as the model, I've knocked 40 off for a max MSS number of 1452 for the TCP stack to use.
Code:
ndd -set /dev/tcp tcp_mss_max_ipv4 1452
In addition to this I'll want to turn off Path MTU Discovery.
When discussing inodes and data blocks, I know Solaris creates these data blocks with a total size of 8192b, divided into eight 1024b "fragments." It stores data in "contiguous" fragments and solaris doesn't allow a file to use portions of two different fragments. If the file size permits, then the... (4 Replies)
Greetings, and thank you for your time.
I am cracking the whip to self-teach myself Unix because I think it will be the best platform for me to really open my mind and be creative. Sadly I lack anyone experienced in Unix to nag with questions, so you will be seeing a lot of me here I am sure... (4 Replies)
Hello People,
Please can someone help me with destination IP address NAT and Port transalation using ipnat in Solaris 8.
Scenario: Box A(192.168.100.1/24) and Box B (192.168.100.50/24) are connected phyically and logically(vlan) on the same network switch.

Hello,
| am trying to setup ipfilter on solaris express snv_91 but I don't seem to have the following file available.
/etc/ipf/pfil.ap
Is this an older way of configuring the interface?, I have all the packages installed.
Thanks, (1 Reply)
Simply question which should I use. correct me if I'm wrong but Solaris Express is taking the place of Opensolaris and is officially sanctioned by Oracle and OpenIndiana is what used to be OpenSolaris.
If I opt for OpenIndiana is it going to follow the official Oracle Solaris releases or are... (3 Replies)
Hi all,
I decided to replace my linux router/firewall with Solaris 11 express. This is a pppoe connection directly to my server...no router boxes. I got everything setup, but the performance is terrible on the NAT....really slow. A web page that loads on the server instantly will take... (3 Replies)

bootparamd
BOOTPARAMD(8) BSD System Manager's Manual BOOTPARAMD(8)NAME
bootparamd -- boot parameter server
SYNOPSIS
bootparamd [-ds] [-r router] [-f file]
DESCRIPTION
The bootparamd utility is a server process that provides information to diskless(8) clients necessary for booting. It consults the
/etc/bootparams file.
This version will allow the use of aliases on the hostname in the /etc/bootparams file. The returned hostname to the whoami request done by
the booting client will be the name that appears in /etc/bootparams and not the canonical name. In this way you can keep the answer short
enough so that machines that cannot handle long hostnames will not fail during boot.
OPTIONS -d Display the debugging information.
-s Log the debugging information with syslog(3).
-r router The default router (a machine or an IP-address). This defaults to the machine running the server.
-f file The file to use as boot parameter file instead of /etc/bootparams.
FILES
/etc/bootparams default boot parameter file
EXAMPLES
When netbooting diskless SunOS/Xkernel SPARCstations the booted SunOS kernel also broadcasts to the all-0 address. The SunOS kernel hangs
until it receives a reply. To accommodate this behaviour add an alias address that responds to an all-0 broadcast. So, add something like
'ifconfig xl0 192.168.200.254 netmask 255.255.255.255 broadcast 192.168.200.0 alias' on the relevant network interface on your bootparamd
server. The alias address must of course be free for use.

BUGS
You may find the syslog(3) loggings to be verbose.
