I guess I figured as long as we're dealing with static internal IPs that
can be reached when the PPTP tunnel is established I could work around a
dynamic WAN IP address. I made the bridge with the EoIP tunnels and the
specified interfaces with a matching remote ID, etc.
The only other thing I can think of that I haven't tried is changing the
MTU. Right now the EoIP tunnel and PPTP tunnel are set to 1500, but I
think the PPPoE client into Qwest is set to 1480 - I don't know if it
will break things to change this to 1500, but I've seen mismatched MTU
settings cause strange issues before.

Kind of. The config points to an IP. If the IP changes you'll need to
update the config. You can write a script to combat this (kind of a
hassle...)
Config is pretty much just make a new bridge, include said eoip tunnel and
the interface to bridge and then make the eoip tunnel config match (that is
tunnel ID and destined IP).

Hi Everyone,
I'm trying to set up an EoIP tunnel between my main location and a remote
office and am having a little difficulty making it work. I was able to get
it to work in lab, but I can't seem to make it work in the real world.
First question: do you need to have a static public IP address at both ends
of the tunnel for it to work properly? I'll try to explain my set up with as
much detail as possible.
I've got a RB1000 with 5 public IPs and 4 different subnets, all restricted
communication via firewall rules. I'm trying to bridge access into my
primary subnet which is 192.168.1.0/24. All of my PPTP connections come in
and are assigned an IP address in the 192.168.2.0/28 range - communication
with the 192.168.1.0/24 subnet is allowed through the firewall rules and I
have no problems with access here.
I've set aside a PPTP username for the remote office, given it a static IP
on the 2.x subnet and the PPTP tunnel comes up fine. The part I'm confused
on is with the EoIP tunnel and the remote endpoint IP addresses I should be
using. On my RB1000 (192.168.1.254) I have the remote endpoint as
192.168.2.11, the IP of the PPTP client for the remote office. At the remote
office (an RB750) I've got the endpoint set to 192.168.1.254, figuring once
the PPTP tunnel is up it should see this IP address just fine. No dice.
Even when I disable the EoIP tunnel and try to ping from winbox, I can only
ping something on my 1.x subnet when I specifically set the PPTP Tunnel as
the interface (instead of using "any").
The remote end is a DSL connection that uses PPPoE.
I guess at this stage I'm just looking for a few pointers as to how this
*should* be set up.
Thanks!
